New Resistor Color Code

Some Chinese kits have odd color codes so I always check with an ohmmeter. Just saw this in a PDF. Check that crazy bottom 5-color band explanation. Who knew?

Besides, there are no colour codes on SMD resistors!
Having said that, your example looks quite reasonable.
No big deal, I never remembered the color code anyway. At least they measured correct.
Then there are those crazy four-band ones with equally spaced bands where you get a different answer depending on which end you start from:
brown, red, black, black, brown = 120 ohms 1% tolerance. Turn it over and you get:
brown, black, black, red, brown = 10k ohms 1% tolerance.
Does it still hold true if the body color is blue it's a metal film resistor and if tan it's a carbon?
Then a couple of years later there was one kit that drove me nuts, it just wouldn't work at all, I tested and retested everything until I realized that it had the same problem. I desoldered the LEDs and flipped them opposite of the silk screen and it was fine.
4 band color represents- First digit: Second Digit : Multiplier : tolerance
5 band color represents- First digit: Second Digit :third digit: Multiplier : tolerance
6 band color represents- First digit: Second Digit :third digit: Multiplier : tolerance : temperature cofficient
If you can see the color clearly then there are lot of Calculators available online to calculate the resistor value like this resistor color code calculator and there is a very nice application for mobile phones ElectroDroid which have many Electronics Calculators.
But some times its very hard to see the colors and you surely need a multimeter for find its resistance value.
Heh... let's not forget those color bands that are like 0.1mm wide!

When I was a kid pulling components out of broken TV's a radios resistors were colour coded as "body tip spot":

You are showing your age! Unfortunately remember them too
