The motherboard comes with an easy to use AURA app that allows you to customise the RGB LED lighting with various effects including breathing, static, colour cycle, audio sensitive and CPU temperature sensor. You can also turn it off if you are that way inclined. The CPU temperature sensor mode is surprisingly awesome, ranging from green-yellow-red representing cool to hot, this is a feature I believe will capture the attention of many enthusiasts.
The colours are solid, sensitive, and accurate, showing high quality RGB LEDs used. The white looks white, green looks green and every colour between is well captured. Directly looking at the LEDs you can see the combination colours used to make the desired hue, however when it is inside your case, it is unlikely you will see such a detail.
