I think the ClipTest node is very useful - I’ve started using it to make sure my packshot background is fully white.
What I notices however is - it’ll show the same for clipping all three channels (R, G, B) a when it clips just one.
I think it’d be very useful to see which channels are clipped.
It could go with gray for all three, but show red, green, blue, yellow, teal or pink for other combinations of clipped channels.
What do you think?
