Michael Harding Copper Phthalocyanine Green - This rich color probably ties with Phthalo Blue and Deep Purple as the strongest pigment in the range. Atomic Tint Power, add it with great care! Ferocious acidy blue-green hues and blue undertones come to prominence in mixes with yellows. In common with the Blue it displays, on curing and when used virtually unmixed, a certain tendency to show surface bronzing. The ruination of many a student’s work, use with great caution!
