This is off topic, but there exist good tools to do conversion to 256
colours. For most images, conversion can be done without visible quality
degradation.

My favourite tool is Neuquant:

Often you don't even need dithering with this incredible quantizer.

You get even more astonishing results from Image Optimizer. It
dynamically calculates which parts of the image need dithering and which
parts of the image suffer from quality degradation while dithering and
then does the conversion with a good quantizer. It's Windows only
unfortunalely:

Now, on topic, KDE's 16x16 pixel icons only consist of 256 pixels an can
be converted without quality loss. The larger icons usually use more than
256 colours, but are an easy job for any quantizer, even the poor ones
from Netpbm and Gimp.
