Welcome to the forum, @dennoneuro!

The Colour Deconvolution plugin comes bundled with the Fiji distribution of ImageJ.

In Fiji, you can press L to bring up the Command Finder and then type decon into the Search box. You should see “Colour Deconvolution” in the list. Press ↓ and then enter to run it from there.
