10 Reasons to Use Color

in Visual Design

Color is an element of visual language that people process before they are consciously aware of it. It ‘pops out’ at viewers in the early stages of vision. Because color is a potent element of visual communication, we need to think through how and why we are using it. Here are ten reasons why you might want to use color in your visual messages and displays. But first, please read this note about color and accessibility.

A Note About Accessibility: The solitary use of color to convey information leaves many visually impaired persons without the information they require. To keep designs inclusive, use redundant attributes, such as icons, labels or patterns to ensure everyone can perceive the information that color conveys.

1. Use color to speed visual search

Color coding often speeds up visual searchColor coding is a way to convey information quickly, which facilitates visual search. In this Washington D.C. metro map, as with most schematic subway maps, color coded lines represent the different rail lines. Visual searching occurs when we actively scan the environment to locate a specific feature among many distractors. In this case, color makes it easier to visually follow the path of a rail line, speeding up the search process.

2. Use color to improve object recognition

We recognize objects more quickly when their colors reflect what we see in the physical world. Upon seeing an object that is colored differently, like a pink banana, it can cause cognitive dissonance that the viewer must resolve. Of course, you may intentionally use unusual colors as a creative, playful or dissonant approach. But if your aiming for speedy recognition, as in this cover for a children’s book, use colors that are normally associated with an object or scene.

3. Use color to enhance meaning

Bright colors above represent something of valueOur brains are compelled to find meaning, whether it is intended or not. Because the eyes are attracted to bright and high-contrast colors, viewers will derive meaning from something that stands out. When you use color for emphasis, it’s like shouting that this object or element has the greatest value. At the Lynda.com site, the bright yellow is used to prominently display their most important message.

4. Use color to convey structure

Color depicts the structure and “tracks” of a bookColor is often used in technical documentation and textbooks to convey structure. Each chapter might feature a different colored heading and a block of the same color may appear on each page, making it easy to distinguish between chapters. Another approach to color structure can be found in the book, Designing for Small Screens. Each chapter is organized into three sections, denoted by vivid colors. The sections form three tracks running through the book, which is described visually in the table of contents shown above.

5. Use color to establish identity

Colors of Top Web Brands from colourlovers.comIn the sphere of marketing and advertising, brand identity is the visual essence of a business or organization. Visual identity is often highly correlated with color through symbolism (see below). The chosen color, in consort with other aspects of the design, has the potential to project the entire flavor of the organization to the world.

6. Use color for symbolism

Orange is associated with excitement and vibrancyColor elicits both cultural and psychological associations that are symbolic of ideas, concepts and feelings. Context plays a part in color symbolism, meaning that one color can have positive or negative connotations depending on the larger framework. For example, although blue is often associated with strength and optimism in Western cultures, in another context it can be associated with despair and frustration. The vibrant orange tones in the painting above express the energized tension of the bullfight.

7. Use color to improve usability

The wise use of color can improve usability for everything from everyday objects to wayfinding. Consider the glaring red medical waste bags in a hospital, lab or doctor’s office. They help ensure that healthcare workers will deposit infectious materials into the correct container. This concept translates well to the digital world. In user interfaces, color informs users of the most important functions and areas of the screen. For example, in the administrative panel of the Thesis WordPress theme, the large green button (and unusual text) ensure users won’t ever have to wonder how to save their selections.

8. Use color to communicate mood

Two moods expressed through colorMany facets of color—particularly saturation (color purity) and value (range of light to dark)—are known to evoke emotion. But color also creates a mood. Compared to emotion, mood refers to a longer-lasting, milder and generalized experience. Research shows that lighter colors are associated with a more positive affect and darker colors with more negative. Painters and photographers are good at exploiting color value to create a moody experience.

9. Use color to show associations

Color indicates relationshipsOne of the first things we do when looking at a graphic is to group similar items, color being one of the most powerful. For example, Slate Lab’s animated visualization of the US Senate Social Network which is mostly attributed with healthcare software development, calculates which senators had voted alike with each other senator at least 65 percent of the time. Party colors make it easy to see how the senators voted in groups. On the live version (click graphic), the senator’s name displays by rolling over each dot.

10. Use color to express metaphors

Metaphorical language in colorVerbal language is filled with metaphors for color that translate well to visual language. Feeling blue, seeing red and green with envy are common expressions that are easily decoded from an illustration or graphic. In this example, the green facial features against the crackling green sky leave no question that this woman is filled with envy.
