Tips for Reading Resistor Colors
Find the tolerance band first — it's usually gold (±5%) or silver (±10%) and slightly separated from the others. Read from the opposite end.
Memorize the sequence: Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Grey, White = 0-9
Common values to recognize: Brown-Black-Red (1kΩ), Brown-Black-Orange (10kΩ), Red-Red-Red (2.2kΩ), Yellow-Violet-Red (4.7kΩ)
