It would be better if it was opaque, light translucent colors are a pain.
This is a color that is easy to make but easier to buy because I use so much of it. Make it with cadmium yellow light 7:1 Thalo blue for cool yellows or Thalo green for a warm yellows.
Translucent Yellow-Green is opposite translucent Ultramarine Violet and together they darken nicely.
