Got some white oak flooring laid, now need to make it match some
existing red oak i have already. The red oak has been finished with
BLO, and 4 coats of shellac, and one coat of waxless shellac. (in case i
wanted to poly later). Anyone got any suggestions as to how to come
close to making this white oak look like the red? I realize the grain
structure is completely different.

thanks in advance!

I cannot answer or give advice on materials.

Anyway, start with a light stain. You can always darken it. Get too
dark and you can't go back (without more work).
