I'm quite impressed with the color packs available at Deramores.
It takes the guessing game out of a choice you need to make for a matching color pallette.
This is extremely handy for those who find it difficult to color match.
Here's a few that caught my eye, I was on a hunt for blue's and greens recently, but I put my own color choice together, I wish I had of known about these packs then.
Cool Mint Color Pack

Aqua Power Colour Pack in Novita Nordic Wool
