I was wondering what the overlap in duplicate sticks are in the set of 90 portrait set and the set of 90 landscape set and i also have a set of 60 old rembrandts and was wondering if anyone had a color chart for those or could help me identify the name of a stick for replacement purposes. It is the violet without a wrapper. And also what are the blues in the set i noticed one of the blues is a grumbacher blue and id like to just make this set soley rembrandts. The warm bright blues the grbacher one i wonder what the rembrandt equivalent would be. Thank you!!!
