Compliance is the most critical factor. For international projects, RAL 7035 is often required, especially for components destined for European markets where the RAL system is dominant. In the US and Canada, adherence to ANSI standards (including ANSI 70) is often necessary. For electrical control panels specifically, the international standard explicitly states that the external surface should be painted "light grey (identical to RAL 7035)" . In the US market, UL 508A recommends "light gray (identical to ANSI 61)" (slightly darker than ANSI 70).
