To insert this into your library, simply click on the 3-line 'hamburger' on the top right of the library panel, click on 'Import Macros...' and point it at the downloaded file. Then click on the layer for which you want a model and click once on the appropriate macro in the 'Dave's Colour Models' library group category.

About

These macros each create a set of layers for different parts of a set of colour models, some traditional and some new. They aim to be fairly clean in doing this, and so:

Start with a 'Merge Visible' to create a single layer containing the overall view (hence avoiding copying layers with various adjustments that could later cause problems).

Duplicate this layer to form the base for the colour model.

Use simplest methods available (though some need Apply Image which can be slow to calculate).

Name the layers created, so you can see what they are.

Remove adjustments created on the way (such as curves layers) to leave just the model layers.

Use Groups, including a final group as needed so you can treat it as one object and delete it in one go.

Models

Models created include:

RGB: Simple separation of Red, Green and Blue.

RGBW: A new model, adding a White layer much like the CMYK Black layer.

RGB-W: Same as RGBW, but with RGB all in one layer, so you can just have separate colour and tonal layers.

CMY: Inversion of RGB, just with secondary colours Cyan, Magenta and Yellow.

CMYK: CMY with Black 'extracted'.

CMY-K: Two layers, one for colour, the other for tone. Sort of opposite of RGB-W.

HSL: Hue, Saturation and Lightness in separate layers! Lets you do such as paint saturation up and down.

3M Dominance: Three layers, mapping each pixel to the highest (max), middle (mid) and lowest (min) value RGB colours. Useful to create masks and shape colour.

3M Dominance Gaps: The gaps between all pairs of max, mid and min, as monochrome layers (useful for masking/blending).
