Recently I've had three pigments that I use become unavailable. This has led to a couple changes to the color groups that I make. The biggest change is to the group 280-284. Not being able to get the main pigment for this group led me to rethink what I wanted to do with these colors. I liked the aspect of the color getting yellower as it lightened instead of getting paler. First of all I wanted to make the darker color in the group darker and richer. The bigger change came however in the lightest color. I couldn't get a good duplication with other pigments that I had available and I was looking for a good yellow green to use in my tropical set. I finally setteled on the color pictured and then worked with the darkest and lightest colors to make the middle ones.
There were a couple of other colors that also used this pigment but in both cases I've just mixed other pigments to replace the older color. The new colors came very close to the old ones the only difference being that the new colors are not as gritty as the old pigment was. Which, all in all, I can live with that.
