The Vermilion Cliffs

[some glare from wet paint as I took the photo indoors, and it's a bit on the warm side despite selecting the proper WB]
For this, I made some changes in the palette after pulling out some of my paints and doing a color mixing sheet. I don't know if everyone does this, but I certainly find it useful.
Getting tired of the same ultramarine-cerulean blue skies, I used thio green to give a rich turquoise sky. Thio green is a transparent pigment, but it tints wonderfully, probably due to its intensity. I also eliminated the alizarin crimson and replaced it with one of my favorite reds - cadmium red deep, which is a cool, opaque red. I used to mix it with burnt sienna and white to make the perfect equine "nose pink", but with less white and some cad. orange, it makes great Navajo sandstone.
I also added purple lake, which mixes to form a less intense purple-gray for distal cliffs and a nice chromatic black when mixed with burnt sienna and ultramarine blue.
I also threw in the other two greens in my collection: sap and chromatic green. There were also touches of some other colors I was experimenting with: brown madder and cadmium red medium.
Here is what the underpainting/first layer of oils looked like for #30:

And, finally - this evening's sunset. This is the product of a cold front that was predicted to drop some snow. There were flurries earlier in the afternoon, but no accumulation in town. And, it's cold! This is what a snow cumulonimbus looks like:
