Not sure if it is still available - but - a few years back I bought a lovely little gadget at Sherwin Williams called a fandex. It is one of those fans with all the paint colors like you see at the paint counter in the stores. At the time it was about $10 and well worth it. I can look at the colors in my house in the room I plan to use them and know they are going to march perfectly. Works with fabric colors too!!
