Well not really. I made one picture recently that had pink color but I suspected that it was environment issue (orange lights all over the place
About the focusing issue. Well I uploaded 5 pictures to give better perspective but only one is showing up. Don't know why. Anyway its always blurry when I take landscape shots. No matter what I do the bottom of the picture is blurry unless I focus on something that's on the bottom.
Take a look at this picture. Focused on the bike. It's all sharp from the top to the middle of the picture. The lower right corner is blurry and it's happening every time.
