public static final class Color.Builder
extends com.google.protobuf.GeneratedMessageV3.Builder<Color.Builder>
implements ColorOrBuilder

 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.
 This reference page doesn't carry information about the absolute color
 space
 that should be used to interpret the RGB value (e.g. sRGB, Adobe RGB,
 DCI-P3, BT.2020, etc.). By default, applications should assume the sRGB color
 space.
 When color equality needs to be decided, implementations, unless
 documented otherwise, treat two colors as equal if all their red,
 green, blue, and alpha values each differ by at most 1e-5.
 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();
      }
      // ...

      // ...
      static UIColor* fromProto(Color* protocolor) {
         float red = [protocolor red];
         float green = [protocolor green];

         return [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
      }

          CGFloat red, green, blue, alpha;
          if (![color getRed:&red green:&green blue:&blue alpha:&alpha]) {

          }
          Color* result = [[Color alloc] init];

          }
          [result autorelease];
          return result;
