Primer is a waste in this situation. Two coats of paint cover most
colors. Three for drasticly different colors. If three coats of paint
are needed to cover a color, then three it is. Primer doesn't cover.


Are you missing the word "blocking" in the phrase "blocking primer"
accidentally or intentionally?


A blocking primer, as I understand it, keeps stains and some wood
pigments from bleeding through into the PAINT coating.

Yes, and it also is better at hiding hard-to-cover colors such as the vivid
orange and lime green that the OP described.

Has nothing at
all to do with whether the paint that goes on after it COVERS the
underlying color. Entirely different issues.

Not correct.
