SYCSSColor

The simplest use-case to translated CSS color to CGColor or UIColor:

The string has prefix hash(#):

NSString *fuchsiaString = @"#FF00FF";
SYColor *fuchsia = [SYColor colorWithString: fuchsiaString];
//   fuchsia.red == 255;
//   fuchsia.green == 0;
//   fuchsia.blue == 255;

The string is name color, like " fuchsia":

SYColor *fuchsia = [SYColor colorWithString: @"fuchsia"];
//   fuchsia.red == 255;
//   fuchsia.green == 0;
//   fuchsia.blue == 255;

The string is rgb( ) syntax or rgba( ), it's support percent(%):

NSString *fuchsiaRgbString = @"rgb(100%, 0%, 100%)";
NSString *fuchsiaRgbPercentString = @"rgb(255, 0, 255)";
NSString *fuchsiaRgbaString = @"rgba(255, 0, 255, 0.8)";

SYColor *fuchsiaRgb = [SYColor colorWithString:@"fuchsia"];

SYColor *fuchsiaRgbPercent = [SYColor colorWithString:@"fuchsia"];

SYColor *fuchsiaRgba = [SYColor colorWithString:@"fuchsia"];

//   fuchsia.red == 255;
//   fuchsia.green == 0;
//   fuchsia.blue == 255;

Blend Color

When two color blend which One of them must not opaque:

SYColor *red = [SYColor colorWithString:@"red"];
SYColor *green = [SYColor colorWithString:@"green"];
SYColor *blendColor = [SYColor blendFrom:red to:green progress:0.9];

// blendColor.red == 26;
// blendColor.green == 115;
// blendColor.blue == 0;
