Beautiful color reference based on the Ives scientific color theory–the definitive color source for nearly a century. Selecting perfect color combinations has never been easier! By popular demand, Joen Wolfrom has designed a durable, color-accurate, double-sided, multipurpose color wheel that is perfectly sized for use in your studio, workroom, office, or sewing room. It’s easily transportable! One side of the wheel features 24 pure colors with 4 essential color-plan wheels for each color. The opposite side shows a range of each pure color’s tints, shades, and tones. Pure-color wedges are slotted so you can audition colors (fabrics, paint swatches, etc.) alongside them to ensure a perfect match. Includes instructions for choosing colors that work together, taking the mystery out of working with tints, tones and shades .
