Different coloured radiators in different rooms

[Lasvegas]

I am putting in radiators (none currently exist) downstairs in a 1930’s small house. I’m having steel column style (traditional) radiators.

Thinking about having one in lounge black as then it will match the metal of the fire place surround and the grate. The ones in dining room and hall in bronze colour.

in my last house again 1930’s period house, I inherited cast iron column radiators in hall and in conservatory. The other 5 rooms downstairs had white modern radiators. I didn’t think it looked at all odd.

will this look odd? Should they match?

I don't think they need to match, they need to suit the room they are in.
I have different types of radiators in some rooms, and I used to paint the old radiators to match the decor in each specific room.

Absolutely fine. Just make sure the size will keep the room warm.
