Red sky in morning--Oklahoma

Oklahoma morning, 5 1/2 by 8 1/2 watercolor, 140# d'Arches

Oklahoma morning, storm a'coming.
If you don't get up early, you miss brilliant color in Oklahoma and much of nature's beauty.
The old saying "Red sky in morning, sailors take warning, red sky at night, sailors' delight" does apply considering our forecast, but of more delight to me today were the brilliant colors just before sunrise. 
Yes, soon the skies turned gray, but this image, minus the trees bare trees out my window, called for a painting. Blue skies and clouds turning rose colored from the sun still below the horizon, and distance Oklahoma hills.
Colors used, trying to match nature's brilliance--Cobalt Blue, Ultramarine Blue, Cadmium Red, Alizarin Crimson, Quinacridone Rose,  Permanent Rose, Aureolin, Quinacridon Sienna.
