Don't you wish it's easier to create UIColor instances?

#define MO_RGBCOLOR(r,g,b) [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:1]
#define MO_RGBCOLOR1(c) [UIColor colorWithRed:c/255.0 green:c/255.0 blue:c/255.0 alpha:1]
#define MO_RGBACOLOR(r,g,b,a) [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:a]

You use them like:

UIColor* quiteRed = MO_RGBCOLOR(250, 0, 0);
UIColor* grayish = MO_RGBCOLOR1(30);
UIColor* transparentBlue = MO_RGBACOLOR(0, 0, 200, 0.5);
