Strip changes color when filled white I have an Arduino Mega, a WS2812B 5M 300led strip and 5v 20A PS.  I wrote a program that simply lights up all LEDs white.  What I end up with is white at one end, orange in the middle and red at the other.  Nice gradient but not all white.  I can fill it beautifully with red, purple, cyan... but not white. Any ideas on how to correct it?  Thanks!
