@ShadowThePrincessWizard the problem is not the tool, the problem is that actually simulates Cross-stitch
cross stitch has a problem - color zones don't have a border.
to separate two zones of the same color you need a third one in the middle.
and the separator... can't be smaller than a single dot.
From what I know there is a technique to stitch actual lines (can't recall the name - try asking Tink) but obviously the tool doesn't emulate that.
so, less colors mean that you can't actually simulate all the colors in a picture, but more colors can also work against you when you have small dettails
