Any of the following: Replace the handles, eg with wood or steel Paint the melamine - I don't recommend it unless you can do a decent job spray painting Veneer the melamine with veneer or 4mm ply, and varnish/stain/oil the result. Add framing onto the front round the edges - takes very accurate cutting to look good. Buy new doors to fit, theyre not expensive - you need to be able to sort the hinges
The simplest cheapest is just to replace handles.
