WCAG Contrast Check
Compare a foreground and background color. Transparent foregrounds are composited over the selected background before calculation.
Accepts 6/8-digit HEX, rgb(...), or rgba(...). The background must be opaque.

How to use this converter
- 1. Paste `rgb(...)`, `rgba(...)`, `#RRGGBB`, or `#RRGGBBAA`, or enter channels manually.
- 2. Confirm the live text output and preview match the color you expect.
- 3. Use contrast check for text and overlays, batch conversion for token cleanup, and export when the final format is approved.
What gets calculated
This page converts the same color between channel-based and hexadecimal formats. When alpha is present, the converter maps the `0–1` RGBA scale to the `00–FF` HEX pair so transparency stays aligned across formats.
Worked example
`rgba(255, 99, 71, 0.2)` becomes `#FF634733` because `0.2 × 255 = 51`, and decimal `51` is HEX `33`.
Examples you can verify
Opaque color
`rgb(37, 99, 235)` becomes `#2563EB`.
Transparent color
`#1F2937CC` becomes `rgba(31, 41, 55, 0.8)` after decoding the trailing alpha pair.
Review limits and common mistakes
- Do not save `#RRGGBB` when the final token is meant to stay transparent.
- Do not compare RGBA contrast until the foreground has been composited onto the real background.
- Do not copy a computed browser value back into tokens without checking whether your codebase stores the same color as HEX, RGB, or RGBA.
Frequently asked questions
These answers help search engines and AI tools understand what the converter supports.
Can I convert transparency values?
Yes. When alpha is lower than `1`, the converter returns an 8-digit HEX value and keeps the RGBA result in sync.
Which HEX formats are supported?
The converter supports `#RRGGBB` and `#RRGGBBAA`, with or without the leading hash symbol.
Does this tool work without uploading data?
Yes. The converter runs entirely in your browser and does not need a server request to process the color values you enter.
