Selecting perfect color combinations has never been easier! Joen Wolfrom has designed a durable, color-accurate, two-sided, multi-purpose 12" x 12" color wheel for use anywhere you go. One side features 24 pure colors with 4 color-plan wheels for each pure color. The other side shows a range of each pure color's tints, shades, and tones. Each color wedge is slotted so you can audition colors easily to ensure a perfect match.
