PURPOSE: A colored lamp capable of emitting light which is as good as natural light and of being controlled in order to prevent the luminous intensity from going down is provided. CONSTITUTION: The colored lamp according to the present invention comprising: a bulb(2) having a cobalt layer(6) formed on an outer surface thereof and a dielectric material layer(8) formed on the cobalt layer(6), in which the cobalt layer(6) is melted and sticked to the outer surface of the bulb(2) by using a high temperature of heat after applying a cobalt to the outer surface of the bulb(2); and a dielectric material layer(8) formed on an outer surface the cobalt layer(6), in which the dielectric material layer(8) is formed by alternatively depositing a dielectric materials having a high refractivity and a dielectric materials having a low refractivity onto the outer surface of the cobalt layer(6) by using a vacuum deposition technique.
