Karl,
Chromium Trioxide makes a great color at first. But with exposure to the sun, It WILL turn green. I had to repair the first gun I ever built because of it. It ended up looking quite nice, but had to stain over that nice green tinted wood.
IMHO, Aquafortis, is the prettiest, most PC stain. But I find it difficult to wave a torch or heatgun over a finely relief carved piece of wood. So mostly I use alcohol based stains. LMF has about the best selections of colors, and the best thing is that you can mix them to get what you want, either in the can or on the wood.
DO NOT use oil stains on maple, it just muddies up the curl. :nono:
Good Luck :grin:
