Well, time to update with the info gained from my research:
Browsing the Warstore's page for the airbrush paints, I was surprised to see there weren't color swatches...at least not that I saw. The regular paints show the color, but nothing for the airbrush colors.
So, no problem...I'll track down the Vallejo website for the colors. Found a nice
page with all the colors in the line displayed...but was a little concerned when looking at the yellows (especially) I was interested in, as they all looked really gray. Quick check of the video card, monitor and some test pages showed the computer CAN show yellows, so it must a website issue.
There was, however, a
table showing how to match the airbrush colors to other lines' colors. Checking the colors on
Federal Standard Color Server proved very useful, with large, easy to distinguish color swatches.
The Vallejo site also had an
interesting guide on how to use their product and airbrushes. A few more steps than I had been using (
lol), so that may help a bit, too.
