How to Compare HEX and RGB Colors
Compare colors by entering their HEX, RGB, or HSL values and checking the numerical and visual difference in the same color space.
FileCompare processes supported inputs in the browser, so the content stays on your device. Open the Color Compare tool when you are ready to compare two real versions.
Steps
- Enter the first color value.
- Enter the second color value.
- Convert values when necessary so the comparison uses a consistent representation.
- Review the swatches and copy the values for your design system.
What to Check
- Use the same color profile in design and code workflows.
- Check contrast separately when accessibility is the goal.
- Treat a visually similar color and an identical token as different requirements.
When This Workflow Helps
This workflow is useful before a deployment, document handoff, content publication, data import, or QA sign-off. It gives reviewers a compact record of what changed without requiring a desktop suite or command-line setup. For structured formats, review the semantic meaning of the changes after the visual diff; for text formats, confirm that formatting noise is not hiding the important edit.
Limits
Color comparison does not replace an accessibility audit or account for every display and color-profile difference.
Try the Tool
Start with a small sample so you can confirm the comparison mode and output before opening a large file. Open Color Compare.
