I thought I would put this idea that my fiance came up with to help me with my painting. She recently took some old business cards that we had collected over the past year and turned them into paint id cards for me since I have partial color blindness, she painted swatches of the various colors of grey that I use for Deck Grey so I could see what they looked like dry. To be honest this really helped me out since I have actually used the true deck grey when I was in the navy. She went on to Vista Print and ordered me a 1000 cards that she designed for under $20 to help me id my paints and to remember any mix ratios for any custom colors that I mix.
