Which color represents the digit 9 in resistor color code?

Resistor color code uses colors to stand for digits 0 through 9. The mapping is black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, gray 8, and white 9. So the digit 9 is represented by white. In practice, the first two bands on a resistor indicate the significant digits, so a white band would contribute a 9 to those digits. The other colors correspond to other digits (black = 0, brown = 1, violet = 7, etc.), which is why white uniquely represents 9.
