STEP ONE

Mixing Permanent Alizarin Crimson, Winsor Green (blue shade) and Phthalo blue for the darkest darks.  This is a bit interpretive and if you paint and follow the shapes, the spirit of the glass will come through.  For the darkest values of the gold/yellow on this perfume bottle, I mixed quinacridone gold with permanent alizarin crimson and a hint of phthalo blue.  I am setting this up for the mid to dark values to be painted in next.
