// Example CSS for a button using your palette
.button-main {
    background: #234080;
    color: #fff;
    border-radius: 8px;
    border: none;
    transition: background .16s;
}
.button-main:hover {
    background: #17A2B8;
    color: #fff;
}

Common Color Mistakes to Avoid

  • Too little contrast between background and text—check WCAG guidelines.
  • Overusing saturated or neon colors—these can fatigue users and look unprofessional.
  • Ignoring color blindness—always preview your work with simulated deficiencies.
  • Using too many colors—limit your palette for cohesion and simplicity.

Accessible Design: Why Color Matters for Everyone

Digital accessibility is both a best practice and a legal requirement. The WCAG (Web Content Accessibility Guidelines) set standards for color contrast to ensure web content is readable for users with visual impairments. This means:

  • Text and background color contrast must meet minimum ratios (e.g., 4.5:1 for normal text).
  • Designs must be usable for people with color blindness or low vision.
  • Information should not be conveyed by color alone—use icons, labels, or patterns as well.

Frequently Asked Questions: Color Tools & Accessibility

The best approach is to start with a tool like our Palette Generator, which suggests harmonious and accessible color combinations. Always verify color contrast with a Contrast Checker to meet WCAG standards. Simulate color blindness to ensure all users can distinguish important elements, and avoid using color as the only means of conveying information.

Online color tools automate the process of checking contrast ratios and simulating real-world vision conditions, making it easier to comply with accessibility laws and guidelines. Using these tools ensures your site is usable by everyone and helps avoid legal or reputational risks associated with non-compliance.
