Layering ..
Welcome, Arthur.
It sounds like you're layering a dark (black, brown, etc) on top of existing paint. This "sinking in" that you're experiencing happens to us all. It'd take a real master (like Virgil Elliott) to explain the chemistry going on. I can see Virgil shuddering as I write this, but I like the judicious use of retouch varnish to "bring the color back". There's opinion about how archival a painting can be with intermediate use of retouch, but I like it a lot.
If you're patient enough (I am NOT), you can wait the full six months for a painting to dry, and then when you put your final varnish your darks will "rise again".
I'll be curious to see what others do (or don't).
