This ImageJ plugin shows the color distribution within a 3D-color-space. The viewing angle can be adjusted with the mouse.
Eleven different color spaces and five display modes are supported. By switching between color spaces - the relationship between different color spaces can be made visible.
In addition the effect of image manipulations can be studied on an image and the corresponding color distribution.
This plugin can be used with all image types. In addition it contains several typical example images.
If a ROI or a freehand mask is used, then only the colors within this region will be displayed.
