For the Lexus IS-F, start with the make-specific code guidance: Lexus, manufactured by Toyota, shares many color codes. On all models, a color ID plate on the driver's door jamb shows C/TR followed by the paint code. Example: C/TR 3P1 FA09, where 3P1 is the color code; FA09 is an interior option code. The same paint can have different names across models (e.g., 3P1: Impulse Red Metallic Clearcoat, also Red Metallic Clearcoat or Wine Metallic Clearcoat). Dealers can provide the color code via VIN. If the label is missing, ask a dealer parts department for a VIN lookup before ordering paint.
