Which practice improves accessibility when designing color palettes and graphics for the web?

• A. Ensure color contrast meets guidelines.
• B. Rely on color alone to convey information.
• C. Avoid providing alternative text for accessibility.
• D. Rely on hover states for all navigation.

Answer: (A)

Making color choices accessible means ensuring enough contrast between text or important graphics and their backgrounds so content is readable by people with low vision, color vision deficiencies, or those viewing on different screens. When color contrast meets guidelines, text remains legible, UI elements stay distinguishable, and information isn’t communicated by color alone. This directly supports readability and discoverability across devices and for keyboard or assistive technology users, which is why it’s the best practice. Relying on color alone to convey information is risky because not everyone perceives color the same way; color cues can be missed by color-blind users or on grayscale displays, so additional indicators like text labels, patterns, or icons are necessary. Providing alternative text for images is essential for screen readers, not something to avoid. Relying on hover states for navigation excludes keyboard and touch users who can’t or don’t use a mouse, so visible focus indicators are needed for accessible navigation.
