RMBP 10.9.3 weird boot up colours?

[Nandifix]

Hello, ever since I updated my early 2013 RMBP to 10.9.3 anytime I boot up the mac it flashes a random colour with the Apple Logo in the middle? First it was yellow and now its red? Everything else is fine though, has anyone else experienced this?

What year/model is it?
Does it have the dGPU?

There were a couple reports of the issue in this thread.

This has been occurring in 10.9.3 since early betas. Allthough annoying, it's nothing to worry about.

Hello
I confirm this issue to be affecting even the late 2013 models with dGPU. Mine flashes pink and then settles back to the original. Tried resetting nvram, pram etc but nothing helped

Ok cheers guys, I guess this is just one of those annoying Apple glitches like when the fans kept spinning up for no reason but a software patch fixed it.

Can someone please try this out ?
Try using a different color profile and does it snaps to the original one when application using dGPU is launched (iPhoto, GarageBand or Photoshop)
