Source: Color_Transformer.java, Installation: Download Color_Transformer.class to the plugins folder, or subfolder, restart ImageJ, and there will be new "Color Transformer" command in the Plugins menu or submenu. Description: This plugin converts an RGB color image into a color space represented by a stack. The XYZ, Yxy, YUV, YIQ, Luv, Lab, AC1C2, I1I2I3, Yuv, YQ1Q2, HSI, HSV, HSL, LCHLuv, LSHLuv and LSHLab color spaces are supported. This plugin does not work on stacks, but the Color Transform Stack macro runs it on all the images in an RGB stack and creates a second stack containing the output images.
Russell Cottrell has created Color Transformer 2, a modified version of this plugin that includes more color management. The original plugin only used the sRGB color space. Color Transformer 2 can now convert from several other spaces, and be customized with the addition of more. It also added a few destination spaces. It is a tool for zone system calibration for those who are not using Photoshop.
