Getting started with CSS Color Name Converter

Map CSS color names to HEX and back. That single sentence is most of what CSS Color Name Converter does—the rest is knowing when to reach for it, which inputs cause trouble, and how it fits alongside the other utilities in the same category.

When CSS Color Name Converter is the right tool

Color work is iterative, so the value of a focused tool is how quickly it answers one question before you move on.

• Modernize named colors to HEX tokens.
• Find the name for a known HEX.
• Teach CSS color keywords.
• Clean up older CSS.

Getting a reliable result

Work from a single base color rather than adjusting several values at once, and keep the output format you actually ship—HEX for handoff, channels when you need alpha. Any pair that will carry text should be measured against a contrast threshold before it becomes a token, because a value that looks fine on one display can fail on another.

• Prefer HEX/OKLCH tokens in new systems.
• Confirm spelling of multi-word names.
• Document renames in PRs.

Mistakes that waste time

• Expecting every HEX to have a CSS name.
• Assuming names are perceptually evenly spaced.
• Mixing deprecated system colors.
• Case-sensitive matching—names are normalized to lowercase.

Privacy and local processing
