Answer
orange, brown, and gold.
Work Step by Step
For the resistance $3.1 \ \Omega$:
The color that corresponds to the first digit, 3, is orange.
The color that corresponds to the second digit, 1, is brown.
Since we need to multiply the number by $0.1$, the third color should be gold.
So we are looking for the colors: orange, brown, and gold.
