// Represents a color in the RGBA color space. This representation is designed
// for simplicity of conversion to/from color representations in various
// languages over compactness; for example, the fields of this representation
// can be trivially provided to the constructor of "java.awt.Color" in Java; it
// can also be trivially provided to UIColor's "+colorWithRed:green:blue:alpha"
// method in iOS; and, with just a little work, it can be easily formatted into
// a CSS "rgba()" string in JavaScript, as well. Here are some examples:
//
// Example (Java):
//
//      import com.google.type.Color;
//
//      // ...
//      public static java.awt.Color fromProto(Color protocolor) {
//        float alpha = protocolor.hasAlpha()
//            ? protocolor.getAlpha().getValue()
//            : 1.0;
//
//        return new java.awt.Color(
//            protocolor.getRed(),
//            protocolor.getGreen(),
//            protocolor.getBlue(),
//            alpha);
//      }
//
//      public static Color toProto(java.awt.Color color) {
//        float red = (float) color.getRed();
//        float green = (float) color.getGreen();
//        float blue = (float) color.getBlue();
//        float denominator = 255.0;
//        Color.Builder resultBuilder =
//            Color
//                .newBuilder()
//                .setRed(red / denominator)
//                .setGreen(green / denominator)
//                .setBlue(blue / denominator);
//        int alpha = color.getAlpha();
//        if (alpha != 255) {
//          result.setAlpha(
//              FloatValue
//                  .newBuilder()
//                  .setValue(((float) alpha) / denominator)
//                  .build());
//        }
//        return resultBuilder.build();
//      }
//      // ...
//
// Example (iOS / Obj-C):
//
//      // ...
//      static UIColor* fromProto(Color* protocolor) {
//         float red = [protocolor red];
//         float green = [protocolor green];
//         float blue = [protocolor blue];
//         FloatValue* alpha_wrapper = [protocolor alpha];
//         float alpha = 1.0;
//         if (alpha_wrapper != nil) {
//           alpha = [alpha_wrapper value];
//         }
//         return [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
//      }
//
//      static Color* toProto(UIColor* color) {
//          CGFloat red, green, blue, alpha;
//          if (![color getRed:&red green:&green blue:&blue alpha:&alpha]) {
//            return nil;
//          }
//          Color* result = [Color alloc] init];
//          [result setRed:red];
//          [result setGreen:green];
//          [result setBlue:blue];
//          if (alpha <= 0.9999) {

//          }
//          [result autorelease];
//          return result;
//     }
//     // ...

//     // ...

//        var green = Math.floor(greenFrac * 255);
//        var blue = Math.floor(blueFrac * 255);
