A colored heat dissipating device comprises at least one heat conductive tube; a plurality of fins combined with the heat dissipating device; each fin being formed with a colored protection film by anodizing processing. Furthermore, a colored heat dissipating device comprises at least one seat; a plurality of fins combined with the seat; each fin being formed with a colored protection film by anodizing processing. Moreover the protection films of all the fins have the same color, the fins are combined with the heat conductive tube by punching. Or the protection films of fins are divided into several sets, the sets have different colors, the fins are combined with the heat conductive tube by punching. Thus the heat dissipating devices is anti-oxidized, erode-proof and dirt-proof. Thereby the indication on the protection film can be used to indicate the specifications of electronic devices suitable to be used therewith.
