Found this info for one supplier

and 5 band colour coding
Markings are to be shown on the resistor body by color coding.
1st, 2nd and 3rd color codes : nominal resistance value.
4th color code: resistance tolerance-J (±5%) - gold color.
5 th color code : fusing characteristics
green color -8 times
blue color -12 times
white color -16 times
violet color -32 times
if 1W then white band means subjecting to 16W will fuse in 1 minute
Surely any normal 1W resistor subjected to that sort of overload will have
burnt up quicker than in 1 minute or have I misread something ?
