# Color Theory for Website Design

_Last updated: 2024-12-05_

Color palettes influence user behavior and perception on websites. Humans interpret colors subconsciously; colors signal action, produce emotions, and influence psychological responses about a brand. Website color choices serve two main purposes: create appropriate engagement and direct visitors through the buyer journey.

## Where Colors Play Important Roles

Website color appears across multiple elements, ranked by importance:

### Imagery and Animations

Images and animations support messaging or distract from it. Current design practice concentrates color distribution on illustrations, images, and animations to create contrast from background and text. When executed well, this creates a focal point without reducing text readability.

### Section Backgrounds

Backgrounds function as backdrops and must be applied carefully to avoid overwhelming the page experience. Color saturation should be controlled to maintain usability.

### Icons

Icons serve a functional purpose beyond decoration. Color directs visitor focus and helps users absorb content.

### Calls to Action (CTAs)

CTA color must be inviting and bold enough to stand out. Text legibility and user interpretation of where the CTA leads are critical. Bold color is not always necessary—if a website is already visually busy, simple black or white buttons with contrasting text may be more effective.

### Fonts

Color contrast between font and background determines accessibility and readability. Colored text or highlights can emphasize messages. Google measures contrast between background and text colors as part of SEO scoring.

### Accessibility

Google measures contrast between background colors and text colors. Low contrast and poor legibility lower overall SEO scores across headers, paragraph text, buttons, tags, and CTA sections. Orange is rarely used on the web due to accessibility challenges (with exceptions like HubSpot). Sometimes palette options must be adjusted to ensure both Google and end users can read all content.

### Visual Contrast

Contrast captures and holds visitor attention. Contrast does not require vibrant colors—bright colors are inefficient if background or images steal attention from key elements like buttons. Dark buttons can be an excellent choice when designed well. Usability should be prioritized over aesthetic preference while adhering to brand palette guidelines.

### Creating Balance

Imbalance causes users to lose focus and leave the website. When using many colors in imagery and backgrounds, fonts and buttons must remain minimalist (black or white). Conversely, text-focused sections may use background colors and CTAs. Either the callout and content or the background should be colorful—not both simultaneously.

### Setting the Vibe

Colors create experience and atmosphere. The goal is not simply choosing which colors to use, but applying them in the right amount to establish the desired vibe. Subtle pops of color on neutral backgrounds can create excitement without overwhelming users.

## Color Coding Pitfalls

Do not assign fixed colors to products, categories, or elements. Creating strict color rules limits design flexibility and can trap designs into predetermined patterns—for example, a purple product page that prevents purple use elsewhere on the site. Use unique colors when needed and allow color flexibility across pages if required by design goals.

## Common Design Traps

### Trap #1: "I want a clean website"

"Clean" can quickly become unreadable if it lacks contrast. Asana exemplifies effective cleanliness: interesting images balance minimal color elsewhere, and simple buttons remain easy to spot. Balance, contrast, and intended vibe should drive palette choices.

### Trap #2: "I want a vibrant website"

Vibrant does not require using all colors on the color wheel. A recommended palette includes one or two main colors and three to four supporting colors. Additional color expression happens through visuals (illustrations, photographs, animations). This approach creates a tidy, consistent website without sacrificing brand palette.

## Purpose of Color in Website Design

Colors separate sections, build rhythm for greater scroll depth, and help companies amplify messages while assisting users in finding what they seek. Brand and website color selection requires careful consideration.
