I have a couple of shades of red and a couple of shades of yellow, so wanted to see how a mixed orange would play out, and then how it would tint. Turns out my Naphthol Crimson (PR 170) is quite close to my current favorite Anthraquinone Red (PR 177). And the light yellow is more of a lemon (cool) color, while the medium yellow is considerably warmer.

I recently bought some Primary Red (PV 19) which turns out to be nearly the same as my Naphthol Crimson (PR 170) — definitely a cool (transparent) red. And I picked up a tube of Transparent Red Oxide (PR 101) and the color is not significantly different from the regular (opaque) Red Oxide (also PR 101) which I already had.

The warm yellow seemed to make more of a difference than the warm red (at bottom — pyrrole red PR 254) as far as the orange was concerned. Meaning, I don’t see much of a difference between the medium cad-free yellow mixed with PR 254, as compared to the same yellow mixed with PR 170.
