There is nothing intrinsic to your construct that loses colour escape
sequences. Try the following:
eval "print -P '%K{blue}Hello'" >&2 >! /tmp/_output
cat /tmp/_output
This should give you a blue background from both commands.
So you might need to take a closer look at exactly what argument you are
passing to eval.
Some commands, make coloured output conditional on whether their
standard output points to a terminal. For an example, try:
git log | cat
