The Hidden Power Problem Destroying WS2812B Strip Colors

Most developers troubleshooting WS2812B LED color shifts blame code and library byte-order issues, but the real culprit is power—specifically, voltage drop along the strip length. When insufficient current reaches the red, green, and blue LEDs equally, their different forward voltages cause color distortion. Solving this requires injecting power at multiple points along the strip and using an adequately rated power supply.
