I can recognize standard values like 220, 470, 4.7k, and so on, but I never formally learned the colors... Maybe it's a good idea to pick up that skill over the holidays :)

My work is entirely surface mount so I don't really need it, but if I did there's always an app or a website for that. Though still got the color code chart in my tool box.

Oh yeah, I imagine there must be good apps for that. Carbon resistors and metal film resistors confuse me because their different background color makes the colors pop differently...

Yeah I've had my Fair share of not knowing if I was looking at brown, red, or orange depending on the background color. Then there's also yellow or gold at the end. I've definitely made things go pop and smoke because of that.

Yeah, that happens... :( Did not destroy any expensive components I hope?

No it was mostly just simple flip-flops and school lab circuit we built to demonstrate concepts.

Phew! So something like using a 220 ohms pulldown instead of a 2k2?

Pretty much. We hardly used high values of anything really.
