 Color codes are individual unicode characters. While you can somehow make a raw character and paste in on your code, it's certainly not desirable. Fortunately, we're also providing utility functions for the color codes.

 ```rgba4444``` takes whole RGBA as input, that is, from 0x0000 to 0xFFFF. Most significant bits represents Red, and least significant bits represents Alpha (which should be fixed as F for the most time)
-``r, g, b(, a)``` takes RGB and A separately, in the range of 0..F. Any value exceeds the range **are unchecked and may wreak havoc**, so be careful.
