OSX 10.9.3 Weird Boot

[SimplyMac2012]

I hope i don't have a problem but since the last update when my MacBook Pro 15" with retina starts up when the Apple Symbol appears on boot just before i log in the display goes yellow for 2/3 secs.

Is this the normal ?

Try resetting the pram Other people have reported odd anomalies like that and resetting the pram fixed the issue.

I would not say it is "normal", but you are not alone. I have seen a couple threads here since 10.9.3 came out with users reporting 10.9.3 caused odd color flashes in the Apple at startup. So I don't think it is anything wrong with your system, but more a bug in 10.9.3.
