Here is a comparison image of Venus on March 22 and 23.

In both cases I used UV as luminance (and UV = W47+BG39)

Then the RGB was mapped like this:
march 22: R-(g)-UV
march 23: IR-(g)-UV
where (g) is a synthethic green channel (just the average of the other two). On March 22 I didn't capture IR, so I just R for red ;) The IR and R recordings were very much comparable, as I didn't process them hard at all (so all the color information basically comes from the UV channel).
