I think it's better having only the main switch a different colour, making it easily identifiable.
Yeah I agree, I've always gone along with the idea that the Main Switch on or in a switch-board should have a red toggle on it and no other colour.
All other MCB toggles should be one single contrasting colour.

I've always thought there should be a rule requiring a double pole main switch on domestic boards to cover both tariffs.
Over here until the advent of DIN Rail switchboards, the surface-mounted main switch was always a 2-pole type that de-energised the Hot water circuit as well as the main phase, when the main switch was opened.
Having said that I've never seen a seperate isolator in a DIN Rail board for the HWS, just it's MCB.
