| Purple is not a spectral color (but, if you insist, it falls between violet and red). To describe how light or dark a color would be would be hue and intensity, NOT "shades and tints." Blue, red, and yellow are nothing. Cyan, magenta, and yellow are subtractive primaries; red, blue, and green are additive primaries. Periwinkle, while usually blue, can be a shade of green or violet as well. |
