Hyundai paint codes are normally on the drivers door jamb; some models hide the color code in the engine compartment. Typical format: 3E which corresponds to: Blue Onyx Metallic Clearcoat. Some later Hyundais use a three character code. A paint can be S3; this is actually the same as S3B. Same color code, different name: the same paint may be used across models, e.g., 3E as Blue Onyx Metallic Clearcoat, Blue Clearcoat, or Ocean Blue Clearcoat.
