Question posted in 
I have been trying to solve this app icon color issue all morning. I am still experiencing this after going through both of these highly recommended photoshop/iOS design articles:
- http://davidmckinney.com/blog/2013/12/31/designing-iphone-apps-how-to-setup-photoshop
- http://bjango.com/articles/photoshop/
Here is the problem that I am having:
When creating my app’s icon, the color that I see in Photoshop is the exact same color that I see in xcode’s asset catalog. It is also perfect when I run the app on the iOS simulator.
However, when I run my app on my iPhone the app icon’s color is always darker.
What’s weird, is if I take a screenshot of my iPhone’s screen and email it to myself, the color is correct! So for some reason the color is only darker when you are actually looking at the iPhone’s screen.
Pardon my ignorance, but this is the first design I have ever done for an iOS app and I don’t understand why this is happening or how to fix it.
EDIT: I am now using LiveView after reading this answer: https://stackoverflow.com/a/3597221/3344977
What’s funny is no matter how hard I try I cannot get the color I see on my screen to appear on my iPhone screen. It’s as if this shade of Pink I’m trying to use just isn’t possible to render on an iPhone display.

This is because your iPhone and Monitor screens have different color calibrations (if that’s the right term)
You’re going to want to setup a color profile on your computer that matches the iPhone screens as closely as possible, and use that when developing icons.
Consider turning up the brightness on your iPhone. Go to Settings->Wallpapers & Brightness to adjust it.
In any case, the issue isn’t that the value of the color is changing on your device, it’s just that that color value is being rendered differently.
Its because the resolution of your screen is different than your iOS device try it on other device
