Which color represents the tolerance band in a 4-band resistor with colors Yellow, Violet, Red, Gold?

Explanation:
In a 4-band resistor, the fourth color is the tolerance, telling you how precise the value is. Gold corresponds to a tolerance of ±5%. With yellow and violet as the first two digits (4 and 7) and red as the multiplier (×100), the resistance is 47 × 100 = 4700 ohms (4.7 kΩ) with ±5% tolerance. So the color that represents the tolerance band is gold.
