hey in regards to the extendor, doesn't that make it hard to just the color when your mixing paints on the trey?
Not really. Mix the paints first, then add the extender and mix that in.
Now what I usually do is mix up my batches of colors (keeping track of what I used and how much) until I get the adjustment dead-on, or as close as I can (usually the latter), and only add the extender once I'm sure (I usually paint only a section or small spot as paints look different dry than they do wet.) Extender's main purpose, really, is to keep the paint in your mix tray from drying up too quick.
