Working on the large flowers.  Colors are cobalt blue, quinacridone rose (or permanent rose) and titanium white.  Added thalo blue (or winsor blue - green shade) to certain areas.  Watch for deeper values near the flower centers to make them pop.  They are so close in color to the flower....it's a little tricky to highlight them.  I don't finish one area of the painting at a time, so there are more value changes I need to make to the buds on the left, etc.
