Abstract: A color selection mechanism for an integrated color selecting and blending system utilizes a disc having a flat surface with an axial projection therefrom for connection to an airbrush in order to supply selected color paint under regulated air pressure from a group of bottles storing different colors of paint. An opening in a convex surface of the disc opposite the flat surface thereof at a predetermined radial distance from the axis of the projection is connected by a slant bore to the axial projection for passing paint under pressure to an airbrush. A cylindrical block having a concave surface for a tight matching fit with the convex surface of the disc has bores parallel to its axis at the predetermined radial distance. By turning the cylindrical block on its axis, the parallel bores, to which the paint tubes are connected, can be individually selected to supply paint by aligning any one of those bores with the slant bore opening of the convex surface of the disc.
