what is the difference between the colors of bell peppers
Bell pepper The most common colors of bell peppers are green, yellow, orange and red. More rarely, brown, white, lavender, and dark purple peppers can be seen, depending on the variety. Most typically, unripe fruits are green or, less commonly, pale yellow or purple. Red bell peppers are simply ripened green peppers,[12] although the Permagreen variety maintains its green color even when fully ripe. Green peppers are less sweet and slightly more bitter than yellow or orange peppers, with red bell peppers being the sweetest. The taste of ripe peppers can also vary with growing conditions and post-harvest storage treatment; the sweetest fruits are allowed to ripen fully on the plant in full sunshine, while fruit harvested green and after-ripened in storage is less sweet.[citation needed]
Color wheel The original color circle of Isaac Newton showed only the spectral hues and was provided to illustrate a rule for the color of mixtures of lights, that these could be approximately predicted from the center of gravity of the numbers of "rays" of each spectral color present (represented in his diagram by small circles).[7] The divisions of Newton's circle are of unequal size, being based on the intervals of a Dorian musical scale.[8] Most later color circles include the purples, however, between red and violet, and have equal-sized hue divisions.[9] Color scientists and psychologists often use the additive primaries, red, green and blue; and often refer to their arrangement around a circle as a color circle as opposed to a color wheel.[10]
