Differing sizes are no problems. Prominent example: if you have picture
with an aspect ratio other than 1, the thumbnail won't be square. The
file managers usually handle that quite fine ...
The spec actually says that thumbnails for small images don't have to be
saved; though in practice I'd expect that a 32x32 sized thumbnail shows
up as 32x32 (and not scaled up or so).
Colors: spec says “it must be a 8bit, non-interlaced PNG image with full
alpha transparency”. It's somewhat ambiguous, but indexed colors seem
unlikely - 32bit RGBA images (ie 8 bit per channel) is what every
thumbnailer practically creates.
