The term blue may refer to any of a number of similar colors. The sensation of blue is evoked by light having a spectrum dominated by energy in the wavelength range of about 440–490 nm.
Blue is considered to be one of the three primary additive colors. Blue light has the shortest wavelength range of the three additive primary colors.

Blue is blue, and since it's a primary color, it's not made of any other colors.
