One is green, red and black, the other Blue is very small and bright. Is there a way to differentiate? Do you need some kind of instrument, and he would in such cases? I know that these figures as they came up with a plan and a kit

The colors do not help. It is probably one of the three two-digit number that gives the value (I think) nanofarad, 1e-09 F. They function like the color codes of the resistance 474 is 47 x 10 ^ 4 nanofarad. Figure out there.
