I tried reproducing this in Emacs 29.  It does indeed still need `C-q'
to enter the space, but after doing that, it seems to actually do the
rest correctly.

I did:

M-x set-face-underline RET
default RET
(:colorC-q "red") RET

and the default face got a red underline.

The `C-q' should be fixed, but do you also see the same behaviour for
the rest?
