It would seem to me that adding color to the top coat would mean that as

when you reapply polyurethane at some point down the road, you will

stand out.

Greetings,

If you add stain to the polyurethane it should be done in the first
coat only (as I understand it). So long as you do not wait until you
get down to the first coat of polyurethane before recoating it should
never be a problem. If you were concerned you could put on three coats
of polyurethane instead of two.

Hope this helps,
