True color is the specification of the color of a pixel on a display screen using a 24-bit value, which allows the possibility of up to 16,777,216 possible colors.
Color is the element of art that is produced when light, striking an object, is reflected back to the eye: that's the objective definition. But in art design, color has a slew of attributes which are primarily subjective. Those include characteristics such as harmony — when two or more colors are brought together and produce a satisfying effective response; and temperature — a blue is considered warm or cool depending on whether it leans towards purple or green and a red whether it leans towards yellow or blue.
