How can one see what value a resistor is given the colors? For example, what's the value of Red - Orange - Green - Gold?
I'm trying to recycle an old cell phone charger to power something else. I've cut the tip off and I see 4 wires... with following colors: red, green, blue, and yellow. I can't figure out which ones ...

How do I tell which wire is which if I have a copper wire, red and green coded wire? Is the unshielded copper wire ground?
The title says it.
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 ...
I know the values of resistors if they are gold-colored at the end. When both ends are the same, such as brown-o-p-brown and red-x-y-z-red, I am in problems. How to know which side has the last colour ...
