GIMP Plugin Registry

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.  read more »

What is Color Spotter? Basically, it's contrast, but "centered" around a color. Another way to see it is as another "Color selection" tool: you specify an image, a kind of threshold, and it selects color that are close to the one you specified; only, Color Spotter keeps every pixel from the image, darkening the wanted colors, brightening the others.  read more »

FX-Foundry/Color/Separate Luminance...

Creates two new layers: one containing the Luminance, and the other the Chroma information in the form of a Grain Merge. Optionally, it will color-enhance (maximize saturation in) the Chroma layer while still keeping it luminance-neutral.

This allows you to do noise-reduction and sharpening on the two layers separately.

Update (23-Jul-2009):
Noticed that highly-saturated colors exceed the ability of the grain-extract/grain-merge to handle without clipping the color, so I have made the excess color get folded into the luminance layer.  read more »

L*C*h (L*a*b* in polar coordinates) color selector module.

Just type "make install" to install this module (You don't need to rebuild the GIMP.) .

This simple plugin was created in response to a request here.

It simply samples the entire image colour, and allows you to either:
- Display the RGB or grey values
- Set the foregound colour
- Set the background colour
- Add it to the current palette (if editable)

There is a toggle to sample just the layer, or the merged image.

It registers in the Colour menu as "Sample Average Colour..." and should work for RGB, indexed, or greyscale images.

UPDATE: Version 1.1 of the script now respects image/layer transparency and selections.

New version:1_3
Add to palette black, gray and white by default.

New version:1_2
Save palette bug fixed.

Version:1_1
Adjust light of scheme work fine (I hope!)

It generates palette by following the harmonic schemes of color: monochromatic, complementary, triadic, tetrad and analogous.
Options:
- you can choose between the digital wheel (RGB) and the real wheel (RYB);
- you can choose whether to use the color "web safe" or not;
- you can see in real time in a preview page the combination of colors;
- you can save a Gimp or Inkscape palette.
Required python libraries: :

This script will create psychedelic 1960's text. I created this script from my tutorial of the same name. I didn't merge the layers in the script, as I did in the tutorial, because you can change the blend modes of the different layers for different appearance.

Rev. 2.0 - added compatability for Gimp 2.4.x

gimp-netpbm2gimp-plugins is a collection of over 200 GIMP plug-ins produced by running the source code of the Netpbm graphics filters through Netpbm2Gimp, which is described below. (Note: Think "GIMP" where the Netpbm graphics filter documentation says "PBM", "PGM", "PPM", "PNM", or "PAM".) There is a particular emphasis on load/save plug-ins for obscure graphics formats, but a number of miscellaneous and useful image filters and image generators are included as well.  read more »

Creates a separate thumbnail of the selected image file(s), pre-pends 'th_' (color image) and 'thgs_' (grayscale image) to the filename. WebThumb takes maxPixels as the maximum size of the largest aspect of the image, and then sizes the opposite aspect to maintain the original ratio.

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.
