As time passes, you will most likely have more and more paint
colors. This is how I easily find them. I have taken various
containers and labeled them with their basic color names.
(These are all oil paints.)
You will also see that I have a small set of colors which I have
left in the box below these containers. In a few cases, I
decided to keep the same brand of paint together.
These are suggestions that might make it easier for you to
find your colors more quickly, if you have quite a lot of it.
But the other thing it does is that you can easily see when
you are low on colors and can restock before you run out!
