sunflower commission

 I am working on a sunflower commission - 30x40" 

and I am trying to match a particular shade of red.

Harder than I thought.

I am so used to using cadmium red light, which definitely has orange undertones.

I'm trying to match the photo of the flowers in the upper left-hand corner.

I ended up mixing napthol red, permanent rose, and a touch of magenta.

I think I got it!

The painting in progress.

I want to finish by Thursday.
