In resistor color code, which color represents the digit 0?

Explanation:
In resistor color code, digits are linked to colors so you can read resistance from color bands. The mapping starts with black for 0, then brown for 1, red for 2, orange for 3, yellow for 4, green for 5, blue for 6, violet for 7, gray for 8, and white for 9. So the digit 0 is represented by black. This color-to-digit relationship is what lets you interpret the values when you see bands like brown-black-red or black-brown-orange. If a question presents the digit 0 as a choice rather than a color, remember that the standard code assigns 0 to black, not to a numeral.
