base64 encoderColors in digital design are expressed in different formats depending on the context. HEX codes (like #FF5733) are used in web design and CSS. RGB values (Red, Green, Blue) define colors by the intensity of each primary color component. HSL (Hue, Saturation, Lightness) is more intuitive for designers to work with. Our tool converts between all formats instantly.
Color contrast is critical for accessibility - the Web Content Accessibility Guidelines (WCAG) require a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text against its background.
