Common questions
Why is my HEX value different in another tool?
Values are clamped to 0-255 and rounded, then written as uppercase HEX. Some tools keep lowercase or invalid input.
What is HSL?
An alternative representation: hue in degrees, saturation and lightness in percent. It is useful for adjusting colours.
Does it check contrast?
No. This converts colour formats; contrast checking is a different tool.
Is this tool really free?
Yes. There is no account, no paywall and no usage limit. Tools App is funded by aumenso, the studio behind it.
