About

Opacitron uses alpha compositing to find a transparent colour that matches an opaque colour on a given background colour.

Warning This tool uses calculations valid in the sRGB colour space. If the colours above do not match, your browser is using a different colour space. Keep in mind that different software might interpret colours differently.
