Varnish can be "paled" by adding 2 drams of oxalic acid per pint of varnish ; it can be colored red with dragon's blood, brown with logwood or madder, and yellow with aloes or gamboge, each dissolved in spirits and strained. W. R. Bowers.

How To Improve The Color Of Shellac Varnish

Occasionally the shellac varnish used by the pattern-maker for varnishing very nice patterns will seem to lose its clear, amber tint. It is frequently the case that the jar is cleaned out and a fresh lot dissolved. This does not always cure the trouble. Any desired depth of tint may be readily obtained by the addition of a small quantity of gamboge previously dissolved in a small quantity of alcohol. It should be kept on hand for this purpose.
