/**
 *
 *
 * <pre>
 * 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.
 * Note: this proto does not 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.
 * Note: when color equality needs to be decided, implementations, unless
 * documented otherwise, will treat two colors to be 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()

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

     * The fraction of this color that should be applied to the pixel. That is,
     * the final pixel color is defined by the equation:
     *   pixel color = alpha * (this color) + (1.0 - alpha) * (background color)
     * This means that a value of 1.0 corresponds to a solid color, whereas
     * a value of 0.0 corresponds to a completely transparent color. This
     * uses a wrapper message rather than a simple float scalar so that it is
     * possible to distinguish between a default value and the value being unset.
     * If omitted, this color object is to be rendered as a solid color
     * (as if the alpha value had been explicitly given with a value of 1.0).
