Your input stays yours
Step by step
- Enter a CSS color such as #ff000080, rgb(255 0 0) or red.
- Choose Convert to see HEX, RGB and HSL representations.
- Check alpha and verify the result against the actual background.
Example: translucent red
#ff000080The last two digits of eight-digit HEX encode alpha. 80 is about 50.2%, not exactly 50%. Output preserves that alpha value.
Frequently asked questions
Why does a color look different on another background?
A translucent color blends with its background. Compare the color, alpha and background together rather than only the HEX string.
Are wide-gamut colors preserved exactly?
Output is converted to sRGB and values outside its range are clipped. Out-of-gamut colors may change; this is not a lossless color-management tool.
Does this check text contrast?
It currently converts formats and previews a swatch. It does not calculate foreground/background contrast or determine accessibility conformance.
