There's a lot of conflicting information flying around the internet on the color accuracy of the new rMBP. Let's get to the bottom of it, shall we? To start, everyone should watch this video and read this article. Now, according to this guy, the retina covers 99% of sRGB, where as the older macbook screens only cover 71%. However... according to AnandTech, the Retina covers 67.3% of Adobe RGB versus 74.7% for the old macbook. Now, it's quite possible that the old mbp's cover more of the Adobe, and less of the s than Retina. But all this info is sending mixed signals to say the least. For most of us, Adobe RGB doesn't matter... sRGB does. And if it does matter, you're going to want a much more expensive display than any laptop has built in.
