An infographic is only as effective as its visual elements. You could have the most compelling data in the world, but if your colour choices clash, your fonts are unreadable, or your icons look like they belong to five different design projects, the message gets lost. The visual elements of an infographic – colours, fonts, icons, and images – are the building blocks that turn raw data into a story people actually want to read. Let’s break down each one and understand how to use them strategically.

The strategic use of colour
Colour is arguably the most powerful visual tool in an infographic. It does far more than make things look attractive. Colour sets the tone of the entire piece. It groups related information, separates sections, highlights key data, and even influences how the audience feels about what they’re reading.
Colour psychology in infographics
Every colour carries psychological associations. Colour psychology studies how different hues affect the way people think, feel, and behave. Red tends to evoke urgency, energy, and passion. Blue inspires trust and calm – which is why you see it so often in corporate and healthcare infographics. Green signals growth, health, and the environment. Yellow suggests optimism and attention, though it can become overwhelming in large doses.
These associations are not just decorative preferences. A health-awareness infographic using calm blues and greens will feel very different from the same content presented in aggressive reds and oranges. The colour palette should always align with the subject matter and the emotional response you want from the reader.
How to build a colour palette
A well-designed infographic typically uses a limited palette of three to five colours. This includes one or two base colours for backgrounds and general sections, and a contrasting highlight colour to draw attention to critical data points. Using too many colours creates visual noise and makes the infographic feel chaotic rather than informative.
There are a few foundational approaches from colour theory that help designers pick palettes that work together. Complementary colours (opposite each other on the colour wheel) create strong contrast. Analogous colours (next to each other on the wheel) produce a more harmonious, blended feel. Triadic schemes (three equally spaced colours) offer variety while maintaining balance.
Colour for grouping and hierarchy
Beyond aesthetics and emotion, colour serves a structural role. You can use the same colour to link related pieces of content, helping the viewer instantly see which data points belong together. Different background colours can separate distinct sections of the infographic, making it scannable. And a single bright, contrasting colour applied to one key statistic or call-to-action immediately tells the reader: this is the most important thing here.
Colour and accessibility
One critical consideration that is often overlooked is colour accessibility. Not all viewers perceive colour the same way. Roughly 8% of men and 0.5% of women have some form of colour vision deficiency. If an infographic relies solely on the difference between red and green to convey meaning, a significant portion of the audience may miss the distinction entirely. Tools like WebAIM’s Contrast Checker help designers verify that their text-to-background colour contrast ratios meet accessibility standards.
Font selection for readability and tone
Typography in an infographic does two jobs simultaneously. It delivers the textual content – the numbers, labels, headings, and explanations. And it communicates a mood and personality, just like colour does. The font you choose tells the viewer whether this is a playful piece, a serious report, or a corporate presentation, before they even start reading.
Serif vs. sans-serif: the basics
Fonts broadly fall into two families. Serif fonts (like Times New Roman or Georgia) have small decorative strokes at the ends of letters. They feel traditional, authoritative, and formal. Sans-serif fonts (like Helvetica, Arial, or Open Sans) lack those strokes and appear clean, modern, and minimal. For infographics, sans-serif fonts are generally the preferred choice because they remain legible at smaller sizes and look crisp in digital formats. That said, a serif font in a title can add a touch of elegance or gravitas when the content calls for it.
Creating a typographic hierarchy
The key to effective typography in infographics is creating a clear text hierarchy. This means using distinct font styles for three levels: the main heading, section headings, and body text. The main heading should be the largest and most visually prominent – it anchors the entire infographic. Section headings should be smaller but still distinguishable from the body. The body text should be the smallest and most readable, since this is where the detailed information lives.
This hierarchy gives the viewer a visual roadmap. At a glance, they know what the infographic is about, what the key sections are, and where to find the details. Without it, the viewer faces a wall of similarly-sized text with no entry point.
The two-font rule
A common guideline among designers is to limit font choices to two or three families at most. A typical pairing uses a bold, distinctive font for headings and a clean, simple font for body text. Using five or six different fonts in a single infographic – a common beginner mistake – creates visual chaos. Each additional font competes for attention, and the design loses its cohesion.
Font size also plays a role beyond hierarchy. In print infographics, body text should be at least 10 points for comfortable reading at arm’s length. For digital or on-screen infographics, 14 points or larger is recommended. If the infographic will be viewed from a distance – say, as a poster – fonts need to be scaled up significantly.
Font personality
Just as colours carry emotional weight, fonts carry personality. A rounded, playful font suggests friendliness and approachability. A sharp, geometric font suggests precision and professionalism. A handwritten-style script font suggests creativity or informality. The font personality should match the content. An infographic about financial regulations should probably not use Comic Sans, just as a children’s nutrition guide probably shouldn’t use a stiff, corporate typeface.
The inclusion of icons for space efficiency
Icons are one of the most underappreciated elements in infographic design. An icon is a simplified, symbolic graphic that represents an idea, object, or action. A tiny lightbulb for “idea.” A shopping cart for “e-commerce.” A person silhouette for “users.” These small visuals do heavy lifting in an infographic because they communicate concepts instantly, without requiring the viewer to read a single word.
Why icons matter
In an infographic – especially one designed for print media – space is limited. Every square centimetre must earn its place. Icons help you replace text with visual shorthand, dramatically reducing clutter. Instead of writing out “total number of smartphone users,” you can place a smartphone icon next to a figure and the meaning is immediately clear.
Icons also break up blocks of text and add visual rhythm to a design. A section of an infographic that is nothing but paragraphs and numbers will feel dense and uninviting. The same content, punctuated by well-chosen icons, becomes scannable and engaging.
Consistency is everything
The single most important rule for using icons is consistency of style. All icons within a single infographic should look like they belong to the same family. This means they should share the same visual treatment – whether that is line-art (simple outlines), filled/solid shapes, or flat design style. Mixing a hand-drawn, sketchy icon with a sleek, corporate icon looks amateurish and distracts the viewer from the content.
Consistent icon usage also extends to colour and size. Icons should use colours drawn from the infographic’s palette, and they should be scaled uniformly so that no single icon dominates the others (unless that emphasis is intentional).
Icon stories
Beyond using individual icons as labels or markers, designers sometimes combine multiple icons into what are called “icon stories.” These are small visual scenes built from icons that illustrate a concept. For example, an icon of a person + an arrow + a building could represent “commuting to work.” Icon stories allow infographic creators to depict simple narratives or processes without relying on text or photographs, keeping the visual language consistent and clean.
Integrating images without overwhelming the infographic
Images – photographs and illustrations – add a layer of realism, emotion, and context that icons and data alone cannot provide. A photograph of a real person, a product, or an environment can ground abstract data in something tangible. An illustration can add charm, personality, or humour. But images are also the element most likely to cause visual clutter if used carelessly.
When to use photographs
Photographs work best when they serve a specific purpose: showing a real-world example, adding emotional weight, or providing context that the data cannot convey on its own. For instance, an infographic about ocean pollution is strengthened by a photograph of a polluted shoreline – it makes the data feel real and urgent.
However, photographs should be used sparingly in infographics. Unlike icons and charts, photos are visually complex. They contain many colours, textures, and details that can compete with the infographic’s data and design elements. Too many photographs can make the layout feel crowded and distract from the core message. A good rule of thumb: if you are not sure why a specific photograph is included, leave it out.
When to use illustrations
Illustrations offer more control than photographs. They can be designed to match the infographic’s colour palette, style, and tone perfectly. A flat-design illustration of a factory, for example, can convey “manufacturing” without introducing the visual noise that a photograph of a real factory would. Illustrations are particularly useful for representing abstract concepts – things like “growth,” “innovation,” or “connectivity” – that do not photograph well.
Best practices for image integration
Regardless of whether you use photographs or illustrations, a few principles apply. First, images should directly support the content. Every image should reinforce or clarify a data point or concept in the infographic. Decorative images that serve no informational purpose are wasted space.
Second, images should harmonise with the colour palette. Photographs with wildly different colour temperatures or tones can feel jarring against an otherwise unified design. Many designers apply colour overlays or filters to photographs to bring them in line with the palette.
Third, images should be high-resolution and appropriately sized. A pixelated photograph destroys credibility instantly. And an oversized image that dominates the layout will shift the viewer’s attention away from the data, which defeats the purpose of the infographic.
Bringing it all together: visual harmony
The real challenge – and the real art – of infographic design is not mastering any single element. It is making all the elements work together. Colour, typography, icons, and images must support one another to tell a unified story. A few principles help achieve this harmony.
Visual hierarchy
Visual hierarchy is the arrangement of design elements in order of importance. The most critical data should be the most visually prominent – through larger font sizes, bolder colours, or strategic placement. Supporting data should be present but less visually dominant. This guides the viewer’s eye through the infographic in a logical sequence, from the most important takeaway down to the finer details.
White space
White space (also called negative space) is the empty area around and between design elements. It is not wasted space – it is one of the most important tools for readability. Sufficient white space prevents the infographic from feeling cramped, gives the eye room to rest, and naturally separates sections. Overcrowded infographics are harder to read and less likely to hold the viewer’s attention.
Consistency across all elements
Consistency ties everything together. The icons should match the colour palette. The font styles should complement the overall visual tone. The images should feel like they belong in the same design world as the charts and icons. When every element follows a unified style guide, the infographic feels polished and professional. When elements are mismatched – clashing fonts, random icon styles, photographs that don’t fit the palette – the infographic feels disjointed and amateurish, regardless of how good the underlying data is.
Ultimately, a well-designed infographic is one where the design itself becomes invisible. The viewer does not stop to admire the fonts or the colour scheme. They simply absorb the information. And that seamless experience is the result of every visual element – colour, type, icons, and images – working in concert.
What do you think? Can you recall an infographic where the colour choices or typography made the information instantly clear – or one where poor design choices made it hard to follow? How much do you think visual elements influence whether people actually engage with the data presented?
