Even though I've replaced my broken "Numeric Edition" LEE Filters swatchbook, I just can't bring myself to throw away all the pieces. Here's what I am thinking: Give the following to a prospective lighting designer who wants to learn about color. Just to make the task more difficult, I've included a "Designers Edition" swatchbook as a guide. And a 1/4-20 x 2" bolt and Nyloc so it won't break again. When the student is done with the above, he/she should certainly know something about Lee colors. Thoughts/opinions?
