Electrical panels are installed in mechanical/electrical rooms or outdoors, there’s zero point in having a cream colored panelboard cover or enclosure. The coating is to protect the metal, not for aesthetics.

Colored conduit is available, but it’s more expensive and specifically used for different low-voltage (under 50V) control wiring, like red for fire alarm wiring, blue for BAS wiring, and so on.
