I don't really recommend warm tone *developer* for prints that
are intended to be toned in polysulfide or selenium toner. The
toned image may suffer significant density loss and excessive
orange or yellow color, especially if used with warm tone
paper stock.

The effect of toning is very specific to the paper emulsion
and you can't really tell from the look of the untoned
image. For example, both Ilford MG4 and Agfa MCP produce
neutral black image when processed in Dektol 1+2, but Agfa
produces significantly warmer toned image, while MG4 remaining
almost neutral black. Both papers are useful, but for
different purposes. (And AGFA paper is no longer available.)
