Color Compare
The gap between two colours is not a single number: how far apart they read, how much they differ in brightness, and whether one is legible on top of the other are three separate measurements. This page computes them from values you type in, and nothing about either colour leaves the page.

Preguntas frecuentes sobre calculadoras en línea
Is the contrast figure a pass or fail verdict?
It is the contrast ratio between the two colours, which is the number accessibility criteria are written against — but the threshold depends on text size and which level you are measuring, so compare it to the requirement you are working to.
Can I enter colours in any notation?
HEX, RGB and HSL each have their own field on both sides, and a picker is there when you would rather choose than type. Whichever you enter, both colours are measured the same way.
Is Color Compare free?
Yes. This tool is free with no trial limit, subscription, or watermark. Use it for personal and commercial projects without an account.
Do I need to install software?
No installation is required. Open the page in a modern browser, add your content, and review the diff immediately.
Can I use this on mobile?
Yes. The responsive layout works on iOS and Android browsers. Paste from your files app or copy results back to your device.
How is this different from desktop diff tools?
Desktop suites offer more plugins but require setup. This online tool focuses on HEX, RGB, and HSL color value differences so you finish reviews quickly from any computer.
What Is Color Compare?
FileCompare.org provides a free online tool for HEX, RGB, and HSL color value differences directly in your browser.
When you need to spot changes quickly, a side-by-side diff beats manual scrolling. Paste content into both panels or upload HEX codes, RGB triplets, and CSS color values, then review highlighted additions, deletions, and edits in one view.
Also known as a color comparison tool, compare colors online, color matching checker, this page is built for developers, writers, analysts, and QA teams who need accurate diffs without installing desktop software.

Common Use Cases
Teams choose an online diff when they need HEX, RGB, and HSL color value differences without a heavy IDE or desktop suite. Typical scenarios include:
- Brand palette consistency checks
- UI theme token review
- Accessibility contrast verification
- Design handoff validation
Because the tool is web-based, remote collaborators can share the same workflow from any location—useful for agencies, open-source maintainers, and distributed QA teams.
Tips for Best Results
Compare colors in the same color space (HEX vs RGB) for consistent results.
When a portal or pipeline rejects your file, compare its encoding, line endings, and size limits with your source, adjust settings, and run the diff again.
