Frequently Asked Questions

Is my data private?

Yes. All colour conversions happen entirely in your browser using JavaScript. No data is ever sent to a server.

Are the conversions accurate?

Yes. All maths follows the official sRGB colour space formulas defined by the W3C and ICC. Rounding is done to standard precision.

What is the alpha channel?

The alpha channel controls transparency. 0 is fully transparent and 1 (or 255) is fully opaque. The RGBA to HEX conversion produces an 8-digit HEX code where the last two digits represent alpha.

Do all browsers support 8-digit HEX?

8-digit HEX codes (#RRGGBBAA) are supported in all modern browsers. For older browser compatibility, use rgba() CSS notation instead.
