Since I bought my set of 72 Prismacolor pencils I have kept them in their original order in the tin, carefully removing individual pencils to color with and returning them to the same slot when done.
The drawback to this was that each of the three trays was a 'step up' from the next smaller set of pencils so had a full range of colors. Each had a few greens, a few reds, a few yellows...
To color a tree, for instance, I might pull and use greens from al three trays and it was difficult to compare tones and tints to find the ones I wanted.
I broke down and pulled all the pencils out of the trays and arranged them by chroma. The first two trays are the rainbow rundown: red, orange, yellow, green, blue, indigo, violet. The third tray contains the two metallics (gold and silver) the white and black and all the browns, warm greys and cool greys.
This arrangement made them so much easier to work from.
I'll show tomorrow the Bible journalling page I worked from this new pencil lineup.
