The Essential Color Card Deck is a set of 200 coordinated color cards, supplied in a box. Each card carries a printed color with its black-to-white value range on one side and practical color information on the reverse, including RGB, CMYK and HEX codes. The deck is based on the best-selling Ultimate 3-in-1 Color Tool by Joen Wolfrom, and it works the way a paint chip fan works: you hold physical color against fabric, thread or paper and judge it in the light you're actually working in, rather than on a screen that shifts with every device.
Value is the detail worth noticing here. Quilters routinely pick a palette that reads well on the design wall and then find the finished top falls flat, because the fabrics share a value even when they differ in hue. Having the black-to-white range printed on the card makes that check quick. A guide covering basic color theory and how to use the deck is included. This listing is for the 200-card deck and box only; no fabric, tools or other supplies are included.
