For creative professionals, one of the most interesting things about the Late 2015 release of the 4K and 5K Retina iMac is that it uses the first wide gamut display Apple has ever made. And the color gamut it uses is not the Adobe RGB gamut usually seen on wide gamut monitors, but a gamut called P3 which is used in digital cinema.
Mac websites have not gone into much detail about this display except to more or less repeat what Apple says in their marketing materials, so I took a closer look at this display in my earlier article, A look at the P3 color gamut of the iMac display (Retina, Late 2015). As I was examining the wide gamut P3 display, I realized that there are several color profiles installed with OS X that I haven’t seen before. What led me to write this article was that almost no one seems to have mentioned these new profiles…and what they have in common.
The Late 2015 Retina iMac includes the first wide gamut display that Apple has made for a Mac, able to reproduce colors well outside the sRGB color gamut. I had questions about the P3 color gamut of the new iMac, so I went over to my local Apple Store to check it out.
Up to this point it’s been a conscious choice to buy a wide gamut monitor. I made that choice when I connected a wide gamut NEC PA272w to my Mac Pro. But now the P3 display is built into all of the new 4K and 5K Retina iMacs, so Retina iMac buyers will now be working with a wide gamut display whether they know it or not. While using a wide gamut monitor is generally a good thing, it can involve certain color challenges.
Every web designer is taught to enter colors in hexadecimal values like #47B56C, but hex code can be like an alien language compared to the traditional RGB and CMYK color values that are familiar to photographers, videographers, and print designers. Luckily, entering colors using simpler RGB values is allowed in CSS, and it’s easy to do.
