U16 colors

Before some applications where using U16 colors so I did that in case it could be useful for someone:

Wow-that's fantastic, thank you. --Pinecone 17:11, 20 November 2008 (UTC)

RGBA Color

It should be noted that there's an even easier way to convert these colors to RGBA than described on the main page. Including the alpha channel is as simple as bitshifting the colour two bytes to the left and ORing it with your alpha channel value.

So, for example, if we want the color RED at half opacity, then we can use:

u8 alpha = 0xFF / 2;
u32 color = (COLOR_red << 16) | alpha;  // 0xFF00007F
