Why Do Color Names Matter?
In web design and development, identifying a color by its HEX or RGB value isn't always intuitive. A descriptive label can make a color easier to discuss than a HEX value. This tool compares the entered color with a reference list using an OKLCH distance, then falls back to a hue-based description when the nearest reference is too far away. The label is an approximation, not an official name for every possible color.
What is WCAG Contrast?
Web Content Accessibility Guidelines (WCAG) dictate how much contrast text needs against its background to be readable by users with low vision. Normally, you need a contrast ratio of at least 4.5:1 for normal text and 3.0:1 for large text to pass the AA accessibility level. This page checks the entered color against white and black and shows the contrast results for those pairs. It does not test every background or every component in your site; use the contrast checker for a pair you intend to use.
Frequently Asked Questions
The result is a nearby descriptive label, not a universal color name. We compare the color in OKLCH against a reference list and use a hue-based fallback for colors without a close match. Use the HEX, RGB, HSL, or OKLCH value when you need the actual color.
The tool displays a generated ramp of lighter and darker values around the entered color. Treat the steps as a starting point: inspect each value in your design and check contrast for any text or control that uses it.
