Another possibly faster way is to use my wipe technique.
Clear coat after sanding.
Spray the color you want to be the TOP color first with oil based paint.
(Orange on the tiger)
Use mineral spirits to wipe off the areas of over spray (parts you want to leave stained.
Clear coat again.
Now spray the lower color.
(Black on the tiger)
Use mineral spirits to wipe it off the over spray areas and off the raised black areas.
Long story short, if you clear coat and use mineral spirits, it wipes off the oil based paint but doesn't affect the clear. Especially with shellac.
You can also easily paint raised surfaces with a sponge brush.
