In this traditional scheme, a complementary color pair contains one primary color (yellow, blue or red) and a secondary color (green, purple or orange). The complement of any primary color can be made by combining the two other primary colors.
In some parts of the world, 'Royal purple' (shown above) or the dark violet color known as generic purple is the common layman's idea of purple, but these color terms carry different meanings in different parts of the world.
The typical artists' paint or pigment color wheel includes the blue, red, and yellow primary colors. The corresponding secondary colors are green, orange, and violet or purple. The tertiary colors are green-yellow, yellow-orange, orange-red, red-violet/purple, purple/violet-blue and blue-green.
In optics, violet is a spectral color (referring to the color of different single wavelengths of light), whereas purple is the color of various combinations of red and blue (or violet) light, some of which humans perceive as similar to violet.
Another practice when darkening a color is to use its opposite, or complementary, color (e.g. purplish-red added to yellowish-green) to neutralize it without a shift in hue and darken it if the additive color is darker than the parent color.
The inverted spectrum is the hypothetical concept, pertaining to the philosophy of color, of two people sharing their color vocabulary and discriminations, although the colors one sees—one's qualia —are systematically different from the colors the other person sees.
The opponent-process theory suggests that there are three opponent channels, each comprising an opposing color pair: red versus green, blue versus yellow, and black versus white ( luminance ). [1] The theory was first proposed in 1892 by the German physiologist Ewald Hering .
The color lavender might be described as a medium purple, a pale bluish purple, or a light pinkish-purple. The term lavender may be used in general to apply to a wide range of pale, light, or grayish-purples, but only on the blue side; lilac is pale purple on the pink side.
In the Munsell color system, magenta is called red-purple. If the spectrum is wrapped to form a color wheel, magenta (additive secondary) appears midway between red and violet. Violet and red, the two components of magenta, are at opposite ends of the visible spectrum and have very different wavelengths.
A complementary color scheme comprises two colors that combine to form gray, i.e. they are on opposite sides of the color wheel. Fully saturated complementary colors maximize color contrast. A split-complementary (also called compound harmony) color scheme comprises three colors, namely a base color and two colors that are 150 degrees and 210 ...
