what 2 primary colors make yellow
Red, green, and blue are the primary stimuli for human color perception and are the primary additive colors. The relationship between the colors can be seen in this illustration: The secondary colors of RGB, cyan, magenta, and yellow, are formed by the mixture of two of the primaries and the exclusion of the third. Red and green combine to make yellow, green and blue make cyan, blue and red make magenta. The combination of red, green, and blue in full intensity makes white. White light is created when all colors of the EM spectrum converge in full intensity.
