I'm trying to convert an integer, 0 to 65536, to a Color object in C#. Originally, I thought about creating a list of all the possible 16 bit Colors and addressing them with the integer, but this is very inefficient.
How can I get the ith possible 16 bit Color object?
A 16 bit color is normally made up of 5 bits of red, 6 bits of green and 5 bits of blue:
rrrr rggg gggb bbbb
To turn that into a 24 bit color that the Color structure represents, you would extract the color components and convert them to the 0..255 range:
int red = color >> 11;
int green = (color >> 5) & 63;
int blue = color & 31;
red = red * 255 / 31;
green = green * 255 / 63;
blue = blue * 255 / 31;
Color result = Color.FromArgb(red, green, blue);
