White is correct for a '21 or '28 Rothmans, Monkey's is a real SP (unlike Mick's) and would almost certainly have been a Rothmans (it's the right age), his Magteks used to be white pre their orange Repsol job, all original white Magteks (like mine) came from Rothmans bikes (or have been bought seperately).
The Cabin and Pentax 21's were gold as were the Rothman's '18's

And white would be nicer if it's a real SP, if it's a rep GP bike then gold, in my humble opinion.
