Resistors are quite small.
We use colour codes in order to be able to fit a lot of information in little space.
Each colour represent a number.
Each band of colour have its own representation.
On a 4 band resistor, the first two are actual values, the third is a multiplier and the fourth is accuracy.
Please check out related question and answer down below for more information.
the resistor have 10 colours they are
1.black
2.brown
3.red
4.orange
5.yellow
6.green
7.blue
8.voilet
9.grey
10.white
the resistor have 3 tolerance bands they are
1.gold +-5%
2.silver +-10%
3.no colour +-20%
The color code on resistors shows the amount of electricity that they each resist. It is important that you use a resistor with enough voltage that you do not damage the electronics.

Thecolorcode of 2.2 ohms resistor is red red yellow silver.

Green Red Brown
The color code is a means of displaying the resistance value of the component, correct to 2 significant figures, on an area where printed digits would be unreadable because of its small size.
The resistor color code use to help to identify the resistance of the resistor. There are four color in the resistor that help to identify the resistance of the resistor. The first and second color represent the numerical value of the resistor. The third color represent the multiplier. The four color represent the tolerance.
Colour code used to identify resistance of the resistor
In electronics, a color code is used to show the value of a resistor. Color codes can be used to communicate just about anything that one might want to.
Yes..... its like the resistor color code
If you want resistor color code, look in wikipedia electronics color code

Thecolorcode of 2.2 ohms resistor is red red yellow silver.

The same way he/she can identify a composite resistor that is color coded or a metal film resistor that is color coded: by reading the color code bands. They all use the same color code. If for some reason the color bands are damaged and unreadable, the resistor will have to be removed and measured with a meter. However this reading may be incorrect as whatever caused the color bands to become unreadable may have also damaged the resistor, changing its value. Verify the value on the schematic!
