Overusing bold hues, ignoring contrast and accessibility, and relying too heavily on trends are a few of the most common color theory mistakes. We’ll explain why these undermine design goals because small missteps in color choice can affect readability, mood, and user perception. Avoid these pitfalls and create color palettes that are visually appealing and effective.
1. Using too many colors
Rainbows aside, looking at too many colors at once makes it hard to focus and leads to visual clutter. It's best to stick to a palette of 3-5 colors. Or consider following the three-color rule that’s prominent in fashion and interior design, which is to have one main color that’s used about 60% of the time, a secondary color (30%), and an accent color (10%). Once you have your core colors, then you can play with tints, shades, and tones to add variety.
2. Relying on saturated colors
Bold, saturated colors should be used with some restraint. They do best when paired with neutrals for balance. Otherwise, if saturated colors dominate the designs, they can come across feeling overwhelming and chaotic. Bold colors are great for accents and highlights, whereas softer palettes often feel more premium — which is something brands need to keep in mind.
3. Ignoring contrast and accessibility
Text and background colors should have the right amount of contrast, so the copy is easy to read. Adobe’s color contrast analyzer comes in handy here. The ideal contrast ratio is at least 4.5:1 for body text. It’s also a good idea to test light mode and dark mode scenarios.
4. Relying too heavily on trends
We’re always communicating with color, and using on-trend colors helps us show that we’re in the know. But on the flip side, relying too heavily on color trends can make your brand seem obsolete (because we all know that trends come and go). There’s nothing wrong with taking advantage of the popularity of a color of the year — in fact, there’s an advantage to doing that, but it’s smart to use it as a secondary or accent color in your brand palette as the trend passes.
5. Misunderstanding color harmony
It may go without saying that using non-harmonious colors results in clashing and unbalanced combinations. This is where harmony frameworks like analogous (colors that are next to each other on the color wheel), complementary (color pairs that are opposite each other on the color wheel), split-complementary (one base color paired with two secondary colors), and triadic (colors that sit at equal distances from each other on the color wheel) come into play. With Adobe Express, you can generate free color palettes in minutes.
6. Forgetting cultural and emotional associations
Color symbolism, the subjective meaning we attach to different colors, is powerful and varies among cultures. For example, the color orange represents warmth and harvest in Western cultures, but it’s associated with mourning in the Middle East. Indian cultures consider orange to be sacred, and in Japan, it symbolizes love, courage, and happiness. Similarly, in the US, brides wear white, but in China, they wear red. All of this is to say that since our perceptions of color are different around the world and may vary by culture, industry, and context, designers need to know their audience. It’s always wise to test color choices with diverse groups, especially for brands.
7. Not considering real-world use cases
Pro tip: Test your color palette across as many settings as you can think of — multiple devices, sizes, formats, and environments. How does it look in actual UI? In print? Or in low-light situations? Make sure the palette works for backgrounds, text, gradients, and buttons. It’s useful to develop a checklist for testing to ensure that you’ve covered all scenarios.
