Original Color Space RGB

Form the opened image the RGB values are read. The distributions of the values is visualized in the 3D RGB space.
By choosing a different color space the color values are converted to the new space which then is visualized.
For the device-independent color spaces sRGB an illumination D50 is assumed.


Here the conversion is show as Java source code.

Luminance / Chrominance Color Spaces
