Disclosed are various embodiments for facilitating the selection of colors. An initial set of colors from a color space is generated in one or more computing devices for rendering in a user interface. Each color from the color space is expressed as a respective tuple of color component values. A selection of one of the initial set of colors is obtained. A subsequent set of colors from the color space is generated for rendering in the user interface. The subsequent set of colors is determined according to values of the N most significant bits of each of the corresponding color component values of the one of the initial set of colors, where N is a predetermined positive integer that is less than a bit length of each color component value.
