I haven't read any posts suggesting that you go and watch some models being flown. If you are in an area where winter hasn't fully halted flying, go to a local club field, look around, watch some planes, see some trainers, talk to some folks. If you can see someone else's airplane easily, you will be able to see one like it if you have one. In these days of RTF ARFs, you will see lots of color schemes in the air that are straight from the box...again - if you can see theirs, you could see one if it was yours.
Forums are great for what they can do.
You need a flying field with some folks using it to help your decisions. Plus, you may just meet someone willing to share with you what they know.
Here's a great link of images of serious hardware in color schemes to keep people alive in real life - aviation training pilots in our military - these color schemes are selected ONLY because of visibility - ground (or sea) to air, and air-to-air. Noteworthy color choices and patterns -
