Colour Match

bleg — Wed, 18 Nov 2009 07:49:16 +0100

Easily map colours from a source colour to a target colour. Very effective for matching skin tones across images or between people.

Relatively quick (but not earth shattering). It doesn't work with grayscale or indexed images. Has preview, works with selections and layers, etc. Very, easy to use, and quite useful for portraits or recolouring graphics.

A demonstration: Lenna's face is mapped to the colour of the feather on her hat. This was done by selecting a colour from her face, then selecting a colour from the feather.

If you have an x86_64 version of GIMP 2.7 on linux, bunzip2 and move the colour-match file to your plugin directory:
bunzip2 colour-match.bz2
chmod 700 colour-match (Make it executable)
mv colour-match ~/.gimp-2.7/plug-ins/colour-match

To build it type: gimptool-2.0 --install colour-match.c
You will need libgimp-dev, and libgtk2.0-dev packages if you didn't build GIMP from source.

The algorithm is based on the relative color remap plug-in by Lars Clausen ( http://registry.gimp.org/node/5442 ).

A Python plugin that start the color scheme designer Agava for creating a new color scheme. The created color scheme can be saved as a Gimp color palette and loaded into Gimp.

Relative color remap

larsrc — Tue, 03 Jun 2008 13:22:55 +0200

This plug-in changes colors in an image based on the HSV difference between two colors. This is particularly useful for applying color themes to existing images.
It avoids burning out high saturation and value at the expense of compression them somewhat when the difference goes towards higher saturation and value.
Current bugs/missing features include:
Undo does not work.
It can't be used on indexed images, even though it would frequently have enough colors.
It's slooow. Since it looks at only one pixel at a time, it should use some "pixel-iterator" that goes through the tiles in an optimal manner.
Selection only works in binary.
Grayscale support is untested and probably broken.
There is no preview.
Prevention of highlight burnout should be optional.

Tone mapping

It reduces global contrast in images while increasing local contrast and shadow/highlight detail. Use this to make your images "pop."

Translucent border

Creates an outer border of the image with reduced brightness and 2 inner colours.

Split tone

Uses one colour for the highlights and another for the shadows. The following photo was created using the default colours:
