Since I did the grey Lakota Pony, it's now time for the other 2. I refer to this guy as 'the flaxen' since it's unclear whether he's a palomino, flaxen chestnut or other pale maned colour.
I've left off the shading to make the colours clearer. All of the colours here are lifted straight from screenshots, using the eyedropper tool.
