Well, this wraps up the three pigment mixes. Some lovely colors here... From now on, I'm back to two pigments with some interesting mixes.
I have twice emailed Winsor and Newton regarding their cadmium mixes and sadly they have disregarded my queries. On the other hand, within an hour of emailing Natural Pigments regarding an overcharge on my recent order, I received a phone call assuring me that their billing mistake was corrected and never made it onto my credit card. Nice going NP! Shame on you, W&N.
