Frequently asked questions

What RGB values are valid?

Each red, green and blue channel uses a value from 0 to 255. Alpha uses a value from 0 to 1.

Does Hex support transparency?

Yes. Eight-digit Hex adds a final two-digit alpha channel, such as #33669980.

Can I convert RGBA to Hex?

Yes. When alpha is below 1, the tool outputs an eight-digit Hex code so transparency can be preserved in CSS.

Why show OKLCH as well as Hex?

Hex is compact for CSS, while OKLCH is useful when you need more perceptually consistent color adjustments.
