Chimerical colors can be seen while seeing with one eye or with both eyes, and are not observed to reproduce simultaneously qualities of opposing colors (e.g. "yellowish blue"). Chimerical colors include:

primary colors, but since the region of real colors is bounded by a smooth curve, there will always be some colors near its edges that are left out. For this reason, primary colors are often chosen that are outside of the region of real colorsâthat is, imaginary or fictitious primary colorsâin order to capture the greatest area of real colors.
