Sap Green, Aureolin Yellow, and New Gamboge combinations are used in light glazes to enhance the leaves. Glazing over the blue underpainting begins to soften the blue into simple, visual shadows of the top glaze of color. This glazing helps to unify the piece as well.
I have added some Burnt Sienna here and there in the background where stems appear and in very thin glazes on some of the leaves. This adds a bit of warmth to the entire area that surrounds the wildly warm flower.
I have also added another very light, watery glaze of Winsor Red to the flower head. I didn't cover every area, only those areas that needed a splash of warmth, especially in the shadowed areas.
