A painting robot for painting motor vehicle bodies having outer faces to be painted on the outside of the motor vehicle bodies and inner faces to be painted in 1the interior of the motor vehicle bodies by means of an atomizer which is guided by the painting robot, wherein the painting robot is suitable both for painting the outer faces and for painting the inner faces of the motor vehicle bodies, characterized by a color changer comprising the following features: a) a plurality of color feed lines (13, 13.1, 13.2) on the inlet side for supplying differently colored paints, wherein there is arranged in the individual color feed lines (13, 13.1, 13.2) a respective color valve (F1, F2,..., Fn) or another color control device which selectively blocks or enables the color feed line (13, 13.1, 13.2), b) a common color line on the outlet side for forwarding the paint selected by the color changer to the atomizer, c) a plurality of docking points which are supplied by the individual color feed lines (13, 13.1, 13.2), and d) a color extractor which can selectively dock onto one of the docking points and, in the docked state, extracts the paint from the associated color feed line (13, 13.1, 13.2) and supplies the extracted paint to the common color line, e) wherein the color extractor and the docking points can be displaced linearily or in rotation relative to one another or can be moved in some other way, and wherein f) the color control devices (F1, F2,..., Fn) are in each case controlled by a control signal, in particular pneumatically by control air, which can be supplied by additional docking points onto which the color extractor can dock, and g) the control signal is passed from the color extractor via the respectively docked docking point to the respective color control device (F1, F2,..., Fn), so that the control signal can reach one of the color control devices (F1, F2,..., Fn) only when the color extractor is docked onto the associated docking point. a) a plurality of color feed lines (13, 13.1, 13.2) on the inlet side for supplying differently colored paints, wherein there is arranged in the individual color feed lines (13, 13.1, 13.2) a respective color valve (F1, F2,..., Fn) or another color control device which selectively blocks or enables the color feed line (13, 13.1, 13.2), b) a common color line on the outlet side for forwarding the paint selected by the color changer to the atomizer, c) a plurality of docking points which are supplied by the individual color feed lines (13, 13.1, 13.2), and d) a color extractor which can selectively dock onto one of the docking points and, in the docked state, extracts the paint from the associated color feed line (13, 13.1, 13.2) and supplies the extracted paint to the common color line, e) wherein the color extractor and the docking points can be displaced linearily or in rotation relative to one another or can be moved in some other way, and wherein f) the color control devices (F1, F2,..., Fn) are in each case controlled by a control signal, in particular pneumatically by control air, which can be supplied by additional docking points onto which the color extractor can dock, and g) the control signal is passed from the color extractor via the respectively docked docking point to the respective color control device (F1, F2,..., Fn), so that the control signal can reach one of the color control devices (F1, F2,..., Fn) only when the color extractor is docked onto the associated docking point.
