Color Cube allows the easy and fast visualisation of the distribution of the colour coordinates of any image in the RGB, CIELAB and HSI colour spaces. When loading an image into the application we can see how the colour coordinates of the pixeles are distributed in the RGB cube. In addition, we can change to other colour spaces such as CIELAB or the HSI cylinder. This information can be used just to check the colour distributino or to select thresholds in segmentation processes. By rotating the space colours it is possible to determine accurately the distribution of the colours.
