take it back and don't stop until you get a perfect one! I bought a rMini last week and was quite disappointed with it. Due to the lower color gamut as well as the yellow tint I had I thought the screen looked terrible and was having buyers remorse. Just got another one yesterday and the screen is perfect! Couldn't be happier. Screen is very bright and although the colors do not pop out like the iPad Air, they still look great. Definitely keeping the mini now.
