Here is one of the most complete component color code charts that I have seen. It covers resistors, capacitors, and inductors for EIA, JAN, and commercial standards. If you are reading this, you have almost certainly memorized the color / number correlation (BBROYGBVGW = 0123456789, respectively) and know how to read a regular carbon resistor's code for resistance and maybe even tolerance. However, if you encounter a capacitor with an array of colored dots or a component with 5 colored bands, are you sure how to read it? This handy-dandy chart will help. Or, you probably have an app on your phone that will do the same thing.
