In resistor color coding, which color represents the digit 6?

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

Answer: (D)

In resistor color coding, each color stands for a specific digit: black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, gray 8, white 9. So the color blue represents the digit 6. That’s why blue is the correct choice for the digit six. In practice, this mapping helps you read the resistance value from the color bands, where the bands indicate digits (and a multiplier). The other colors listed correspond to different digits (gray is 8, green is 5, brown is 1), so they do not represent the digit six.
