A website that converts between different color formats.

Color Formats

Following formats are supported as both input and output, unless otherwise specified.

Hexadecimal Notation

Notation	Description
#RRGGBB	Each pair of R(ed), G(reen) and B(lue) is an integer between 0 and 255 in base 16. Values are given as pairs, therefore single digit values need to be padded with a leading zero. Examples, decimal values to the left and their hexadecimal translation to the right: 255 = FF, 0 = 00 and 10 = 0A.
#RRGGBBAA	Same as #RRGGBB but with an additional pair representing Alpha. Alpha follows the same convention as the color values.
#RGB	Shorter version of #RRGGBB where each values is expanded. Example: #B03 is equal to #BB0033. Note: Supported as input but not output.
#RGBA	Shorter version of #RRGGBBAA where each values is expanded. Example: #9F08 is equal to #99FF0088. Note: Supported as input but not output.

Functional Notation

Notation is based on the standard defined by W3C Color Module. Not all variations are implemented for the input but the output format will be a valid format according to the standards.

Notation		Description
rgb(R, G, B)		Each value R(ed), G(reen) and B(lue) is an integer between 0 and 255.
rgba(R, G, B, A)		Same as rgb() but with an additional value that represents Alpha. The alpha value is a decimal number between 0 and 1.

Float Notation

Notation is based on vectors that define colors using float values. An example would be the vec3 and vec4 data type specified by GLSL.

Notation		Description
R, G, B		Each value R(ed), G(reen) and B(lue) is a float between 0 and 1.
R, G, B, A		Same as R, G, B but with an additional value that represents Alpha. The alpha value uses the same format as the colors.
