Resistor Color Code

Here's an extreme close-up of a ¼ W metal film 20K (20,000) Ohm resistor, designated
by the standard resistor color code.
The colors map to numbers:
Color Number
Black 0
Brown 1
Red 2
Orange 3
Yellow 4
Green 5
Blue 6
Violet 7
Gray 8
White 9
The color band positions have the following meaning (5-band, 1 % resistors):
Position Meaning
1 Left-most Digit (e.g. most significant)
2 Next digit to the right
3 Next digit to the right.
4 Number of zeros that follow the three digits, unless:
 Band 4 is gold => multiply by 0.1
 Band 4 is silver=> multiply by 0.01
5 Tolerance:

Violet (purple) =0.1%
Brown =1%
Red =2%
Gold=5%
Silver=10%
No band=20%
