The color of fruit is quite varied and ranges from the light yellow of the white fruits, through the various shades of red, into deep purple. This condition can better be explained by several examples. Thus, we have the white flesh of the snow peach, followed by pale yellows shading gradually into the deeper colors. Again, we find cherries and plums gradually shading from the yellowish tints through to orange and the deeper reds; and the grapes follow with blues, violets, and purples. Amber and fawn with slight mixtures of grays are also found. In addition to solid color in fruits, we find various striped and mottled effects.
Blotched. Having different abrupt shades more or less blended together without any order or regularity. Blushed. Distinguished from mottled, striped, or splashed by having the surface overspread with a red tint that is not much broken. Clouded. Having blotches broader and more softly shaded and blended together. Dotted. Having small, distinct dots. Marbled. Having wide, faint, irregular, or wavy stripes. Mottled. Covered with dots that run together without any marked lines of distinction. Scarf skin. A term descriptive of a condition found on fruit (principally on apples), which gives a characteristic appearance to the fruit. It usually extends outward from the base in whitish lines, or stripes, readily distinguished by contrast with the green or yellow color. Splashed. Having stripes of color which are much broken and of varying widths. Spotted. Having larger dots than those characterizing a fruit as
"dotted."
Stained. Having the lighter shades of the blotched or clouded effect. Streaked. Having long and narrow color bands. Striped. Having one or more shades of color alternating in broad lines.
