I have color blindness with certain colors, so its hard for me sometimes to see/differentiate certain colors. While turning on my iMac today, i noticed this: To me, I kind of see some yellowish tint towards the bottom half of the screen. And in the second picture, there are some horizontal lines that seem to be darker than the screen. Can anyone else confirm this? Sorry for the pic quality, they were taken from my older 3Gs.
