It wasn't till a few years ago that I actually found the need for making a color swatch chart. I was in a sharpie coloring mode and I could never remember which marker was which color and there's not really a good color chart for them out there.
I made one and then I had to make a chart for everything I owned.
I have space for the color and then a space below for the name and/or number to match.
I also made different size charts. When printed for a book, they're all half a page but I made different quantity sizes for different things. You'll see what I mean.
And, oh, a tip: don't laminate them like I did. I know its tempting, but you'll find you'll need to add colors.
