Here you can select the color space to be used: RGB, HSV... The available options are described in the Decompose command.

Reprezentace kanálů

Allows you to select which layer or image will be used for each channel. You may use this option, for example, to exchange color channels:

Mask Value: Instead of selecting a layer or an image to build the channel, you can give the channel a value from 0 to 255. But note that at least one channel must be formed from a layer or image.

[Tip] Tip

If you use different settings in Compose than when you used Decompose, for instance an image decomposed to RGB then re-composed to LAB, you will get interesting color effects. Test it!
