Some hardware supports 4444 (R,G,B and a 4 bit alpha) - that's somewhat better
than 5551 because you can antialias the edges of your sprites with semi-transparent
pixels.

Of course your colours are now only 4 bits rather than 5 or 6 - so there is a 
downside.

I use 4444 for texture maps in 3D rendering - and they really don't look all
that bad - unless you are trying to use a texture to generate really large
soft-shaded areas.
