Lily Color and Dry Brushing

A bit of dry brushing and experimenting with color mixing. I planned on more today but was thrown off when I discovered a yellow daylily was already in blossom!
So where to begin? Color study? Petal texture? Why not both? I worked with Winsor Yellow, Cadmium Yellow Pale, Cadmium Yellow, Burnt Sienna, Thalo Blue BS, Thalo Green YS, and Cerulean Blue.

At this point, the yellow seems to base fairly well with Winsor Yellow with just a bit of Cadmium Yellow Pale. For green, the Thalo Green as a wash seems okay.

I tried some shadowing with Neutral Tint but ended up with Payne's Gray which leans a bit into blue.
