>>6100998divide them into categories by type, not by color
(unless you've got a limited quantity of something, like all my sand blue is in a separate box)
keep dividing until you've got enough categories that you can find everything easily, and the categories are small enough that you can look through each one easily
for example I'm redoing my sorting system now, and divided my 33-degree slopes into 1x3, 1x3 inverted, 2x3 and 2x3 inverted
then look around hardware stores and shit for decent looking storage, pic related
