I'm having an issue comparing UIColors. I have an image, which I have successfully extracted the color on the image at which the user clicked. Now I want to compare that color with other colors, but I'm getting some strange results. Here's what I've tried: CGColorRef pixelColor = [[buttonImage colorAtPixel:point] CGColor]; UIColor* color = [UIColor colorWithCGColor:pixelColor]; UIColor* aqua = [UIColor colorWithRed:0.521569 green:0.768627 blue:0.254902 alpha:1]; if (CGColorEqualToColor(color.CGColor, aqua.CGColor)) { DLog(@"Apparently, it works"); } DLog(@"%@", color.CGColor); DLog(@"%@", aqua.CGColor); Output: 2011-05-21 19:48:27.144 Coffee[66860:207] -[DescriptorsViewController touchesEnded:withEvent:] <CGColor 0x4d1eb80> [<CGColorSpace 0x4d1a070> (kCGColorSpaceDeviceRGB)] ( 0.521569 0.768627 0.254902 1 ) 2011-05-21 19:48:27.145 Coffee[66860:207] -[DescriptorsViewController touchesEnded:withEvent:] <CGColor 0x4d1f750> [<CGColorSpace 0x4d1a070> (kCGColorSpaceDeviceRGB)] ( 0.521569 0.768627 0.254902 1 ) It looks like the CGColor addresses are different, but the CGColorSpaces are the same, but I can't figure out how to compare the CGColorSpaces I've also tried this: CGColorRef pixelColor = [[buttonImage colorAtPixel:point] CGColor]; UIColor* color = [UIColor colorWithCGColor:pixelColor]; UIColor* aqua = [UIColor colorWithRed:0.521569 green:0.768627 blue:0.254902 alpha:1]; if ([color isEqual:aqua]) { DLog(@"Apparently, it works"); } DLog(@"%@", color.CGColor); DLog(@"%@", aqua.CGColor); The same silliness occurs. 2011-05-21 20:02:49.277 Coffee[67013:207] -[DescriptorsViewController touchesEnded:withEvent:] <CGColor 0x4d3b810> [<CGColorSpace 0x5912010> (kCGColorSpaceDeviceRGB)] ( 0.521569 0.768627 0.254902 1 ) 2011-05-21 20:02:49.278 Coffee[67013:207] -[DescriptorsViewController touchesEnde
