Phthalo Green 🐊This is one of those colours that truly plays well with others. On its own, it is a stunning emerald green, but when mixed with others, it's uses are incredibly diverse. Mix Phthalo with Naphthol Red to get a colour that is near black, or mix Yellow Ocher into it to get a pretty earthy green. Use Phthalo mixed with Ultramarine to create a range of blue-greens. I spent the day making batches of this colour, and I'm fairly sure I'll be dreaming of emeralds tonight.
