I don't mean the colored bands, but the colors of the bodies themselves. They come in brown, blue, green, etc. Is there a standard? For instance, epanorama says: But there are two resistor body ...
WARNING: 30V was a mistake -- better to keep voltage down 12V as a beginner! I tested it over a very short time. Got the things hot over a long time with much less voltage -- apparently not enough ...
