I am assuming the "person" that said "nice yellow" is referring to the scanner/editors not "cleaning" the comic like some scanners/editors do and keeping the colors original as possible.. I myself hate it when the comic is cleaned because the colors get washed out looking.
I hate to point out... but look at some scanner names:
[pmack/chums/gambit - edited colors but usually not too bad and enjoyable. ]
[maddrdoom/greenblast/maxzeus/rougher - over-edited nasty looking white-page or oversaturated edited color I avoid at all costs (sorry folks)]
[jojo/titansfan/comics castle/crx - 99% chance very nicely done]
I also avoid anything that says "DCP" because that team almost always cleans and heavy edits their releases and personally I think they look nasty.
