Color Contrast
Color contrast refers to the difference in luminance or color between foreground elements (like text) and background elements, ensuring readability and visual accessibility. It is a critical aspect of web design and user interface development, measured using ratios defined by standards such as WCAG (Web Content Accessibility Guidelines). Proper color contrast helps users, including those with visual impairments like color blindness or low vision, perceive content clearly.
Developers should learn and apply color contrast principles to create accessible digital products that comply with legal requirements (e.g., ADA, Section 508) and improve user experience for all audiences. It is essential in web development, mobile app design, and any UI/UX work to ensure text is legible against backgrounds, reducing eye strain and supporting inclusivity, particularly in high-stakes applications like healthcare or education.
