I made up this paint chip to help visualize films over different colors. It's a 10 x 24 piece of aluminum I had kicking around. Base coated the whole thing white, then used 2 inch masking tape as a guide to work my way down the piece with the different colors.
These are just the metallics I had on the shelf. I will put the non-metallics on the flip side. These are all OHW, but will make up one for each manufacturer.
