I meant to say why does each LED require a different resistor value?

- dfox 3y agoBecause different colors usually mean different semiconductor material and thus different forward voltage of the junction which in practical terms leads to different brightness if the same resistor value is used.
- ilyt 3y agoDifferent color have different forward voltage and luminosity per mA. Or if it is connected to some live signal the signal itself might be with different voltage range
