Which color corresponds to the value 8?

Which color corresponds to the value 8?

• A. Black
• B. Brown
• C. Gray
• D. Blue

Answer: (C)

Color-to-digit mapping used on resistors is what this item tests. In the standard color code, the digits are assigned as follows: black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, gray 8, white 9. Therefore the color for the value eight is gray. This makes gray the correct choice. The other colors correspond to different digits: black is 0, brown is 1, blue is 6, so they don’t represent eight. Keep this mapping in mind when reading resistor color bands or similar markings in electrical work.
