Practical guide
How to use the color converter
The color converter translates a color between common HEX, RGB and HSL representations. The visible color remains equivalent within rounding limits, while the format changes to suit CSS, design tools or calculations.
Good reasons to use it
- Convert a design-system HEX value to RGB or HSL.
- Prepare a color for CSS variables or programmatic adjustment.
- Compare equivalent notation from different design tools.
A reliable workflow
- Enter a complete supported color value.
- Review the converted representations.
- Test the value against the intended background and accessibility contrast.
How to interpret the result
Equivalent notation does not guarantee accessible contrast. HSL can make lightness adjustments easier, but contrast must be calculated from the final foreground and background colors.
Frequently asked questions
Does the same HEX look identical on every screen?
Not always. Display calibration, color profile and brightness affect appearance.
Can this check WCAG contrast?
No. Convert the colors, then use a dedicated contrast calculation for the exact foreground and background pair.
