Accessible solid color combinations is an art work that to color pair to maintain sufficient contrast between foreground text and its background. A well color contrast is required for creating good looking websites and also easy to read and usable by people with different levels of vision.
The contrast ratio is measured between the text color and background color on a scale from1:1 to 21:1. A higher ratio provides better visual distinction. According toWCAG (Web Content Accessibility Guidelines), normal-sized text should have a contrast ratio of at least4.5:1for Level AA and7:1for Level AAA. This collection focuses on combinations with a contrast ratiogreater than 8:1, providing an additional margin of readability.
Solid colors are particularly useful for buttons, headings, navigation menus, alerts, cards, forms, and content sections because they provide a consistent and predictable visual appearance. Examples include white text on deep navy, dark red, or charcoal backgrounds, as well as black text on light yellow, blue, or green backgrounds.
