Hex to RGBA Converter

Add an alpha channel to a hex color and get the rgba() string, plus the eight-digit hex equivalent. There is also a preview of what the color will actually look like composited over white and over black, which is usually the thing you are trying to find out.

The live converter needs JavaScript. The formula and the worked example below do not. They are plain HTML and will get you the same answer by hand.

How the conversion works

The RGB part converts as normal. Alpha is a value from 0 (fully transparent) to 1 (fully opaque); in eight-digit hex it becomes a fourth pair from 00 to FF.

To find what a translucent color looks like over a background, blend each channel toward the background channel by 1 minus alpha.
