A RYB color wheel with tertiary colors described under the modern definition. RYB is a subtractive mixing color model, used to estimate the mixing of pigments (e.g. paint) in traditional color theory, with primary colors red, yellow, and blue. The secondary colors are green, purple, and orange as demonstrated here:
The web color fuchsia is equivalent to the pure chroma on Munsell Color Wheel of the Munsell color system that is designated as "5RP" (reddish purple) i.e., a purple that is shaded toward red (the color we can achieve today with computers is a much more saturated pure color wheel chroma hue than the original color chip shown on the Munsell ...
