The  electronic color code  is used to indicate the values or ratings of electronic components, very commonly for  resistors , but also for  capacitors ,  inductors , and others. A separate code, the  25-pair color code , is used to identify wires in some  telecommunications  cables. The electronic color code was developed in the early 1920s by the Radio Manufacturers Association (now part of  Electronic Industries Alliance [1]  (EIA)), and was published as EIA-RS-279. The current international standard is IEC 60062. [2] Colorbands were commonly used (especially on  resistors ) because they were easily printed on tiny components, decreasing construction costs. However, there were drawbacks, especially for color blind  people. Overheating of a component, or dirt accumulation, may make it impossible to distinguish brown from red from orange. Advances in printing technology have made printed numbers practical for small compo...
