       "Convert::Color::RGB16" - a color value represented as red/green/blue in 16-bit integers



        use Convert::Color::RGB16;

        my $red = Convert::Color::RGB16->new( 65535, 0, 0 );

        # Can also parse strings
        my $pink = Convert::Color::RGB16->new( '65535,49152,49152' );

        # or
        $pink = Convert::Color::RGB16->new( 'ffffc000c000' );

       Via Convert::Color:

        use Convert::Color;

        my $cyan = Convert::Color->new( 'rgb16:0,65535,65535' );


       Objects in this class represent a color in RGB space, as a set of three integer values in
       the range 0 to 65535; i.e. as 16 bits.

       For representations using floating point values, see Convert::Color::RGB.  For
       representations using 8-bit integers, see Convert::Color::RGB8.


   $color = Convert::Color::RGB16->new( $red, $green, $blue )
       Returns a new object to represent the set of values given. These values should be integers
       between 0 and 65535. Values outside of this range will be clamped.

   $color = Convert::Color::RGB16->new( $string )
       Parses $string for values, and construct a new object similar to the above three-argument
       form. The string should be in the form


       containing the three integer values in decimal notation. It can also be given in the form
       of a hex encoded string, such as would be returned by the "rgb16_hex" method:



   $r = $color->red
   $g = $color->green
   $b = $color->blue
       Accessors for the three components of the color.

   ( $red, $green, $blue ) = $color->rgb16
       Returns the individual red, green and blue color components of the color value in RGB16

   $str = $color->hex
       Returns a string representation of the color components in the RGB16 space, in a
       convenient "RRRRGGGGBBBB" hex string.

   $mix = $color->alpha_blend( $other, [ $alpha ] )
       Return a new color which is a blended combination of the two passed into it.  The optional
       $alpha parameter defines the mix ratio between the two colors, defaulting to 0.5 if not
       defined. Values closer to 0 will blend more of $color, closer to 1 will blend more of

   $mix = $color->alpha16_blend( $other, [ $alpha ] )
       Similar to "alpha_blend" but works with integer arithmetic. $alpha should be an integer in
       the range 0 to 65535.

   $measure = $color->dst_rgb16( $other )
       Return a measure of the distance between the two colors. This is the unweighted Euclidean
       distance of the three color components. Two identical colors will have a measure of 0,
       pure black and pure white have a distance of 1, and all others will lie somewhere

   $measure = $color->dst_rgb16_cheap( $other )
       Return a measure of the distance between the two colors. This is the sum of the squares of
       the differences of each of the color components. This is part of the value used to
       calculate "dst_rgb16", but since it involves no square root it will be cheaper to
       calculate, for use in cases where only the relative values matter, such as when picking
       the "best match" out of a set of colors.  It ranges between 0 for identical colours and
       3*(65535^2) for the distance between pure black and pure white.
