How to Convert a GIMP decomposed Hue Layer to Show Colors?

Processing
1

I have a small utility called ShowImage which decomposes a JPEG into (for example) Hue, Saturation and Value Layers. It can also do HSL and one or two others.The nice thing is that the Hue layer is shown with 100% saturated color for each and every pixel. Thus for a value of 0 or 255 you get red. For 85/255 you get pure green. And so on. Not only does it look pretty :slight_smile: but it can be quite useful.

Now to the point:

In the GIMP, if I decompose an image into HSV or HSL layers, the hue layer is rendered in gray-scale. Is there a way to turn that layer into the same rendition as ShowImage does?

I am no programmer these days (far too old) so an already available GIMP plugin would be nice or, failing that, a Windows stand-alone - I just just about manage a command-line utility!

I don’t do MatLab either, sorry . . .

Once you have decomposed to HSV fill the S and V layers with white, then recompose.
