I still remember the color code phrase I learned in my electronics classes but I cannot repeat it in a family-friendly forum

I'll share the much more family friendly version I use to teach the color code now, but it does lose a bit in the translation:
Bad boys ravage only young girls, but violet gives willingly
for:
black (0), brown(1), red(2), orange(3), yellow(4), green(5), blue(6), violet(7), grey(8 ), white(9).
The code is read from the first band that is part of this color code - the gold band shown in John's post is not, so it is the tolerance code and is on the opposite end from the start of the color code - in this case, gold denotes 5%. The last color band is number of 0's. There is usually a gap between the last color code band (# of zeros) and the tolerance band, so you can use that for orientation. Beware, there are some exceptions that would get too involved to describe here. A gold band in between the color bands indicates a decimal point - for something like 4.7 Ohms. (yellow, gold, violet, black)
So, the 1k resistor, as shown, is (with number of zero's in parentheses) - brown, black, red = 1, 0, (2) = 1, 0, 00 or 1000 Ohms;
the 470 Ohm resistor is yellow, violet, brown = 4, 7, (1) = 4, 7, 0 = 470 Ohms
