This is a pretty decent chart for values by color code.

The carbon types were the common low cost resistor back before solid state circuitry became more common. The type could be off of its design resistance by 15% or more but it would likely still do the intended job.
A lot of newer stuff is metal film or combinations of different materials. The orange, gold, or copper color may or may not be part of the valuation. I don't see brown but colors fade. The width on the edges of the two color bands is wide where there appears to be no color paint but just the black color of carbon and the color bands are usually very uniform in width. The two ends are where it clamps in place so I don't know if those colors mean anything or not.
