RE: Varnish
FYI you can alter the colors of stain by adding universal tint to them to tweak a color to suit your needs, when I worked in a paint store we did it all the time to match colors in WB and oil based stain sometimes combining stock colors to get in the ballpark then pushing the color closer to the desired results with tints.
if you have a good quality store they can match small quantities as small as 1/2 pint
