@Kyresti Diodes have an exponential voltage/current relationship. Little voltage bump makes it go zoom up the curve, followed by BANG if it's a big bump. http://lednique.com/wp/wp-content/uploads/2016/09/IV-curves-all-colours.png

@Kyresti Generally, 20mA max for a 5mm LED is pretty standard, less if you want it to last for a while. 150mA is doing I don't even know what to generate that color shift, but it can't be good. XD
