I have found the Sax brand acrylic paints to be of equal quality to
Chromacryl, except for the yellow. Have also had good luck with the
tempera...except yellow. I think yellows are hard to do and I have found in
less expensive paints (not just Sax but other brands as well) that the
yellows tend to be thin and a little greenish...and never cover as well as a
higher quality paint.
