Plotting an array of functions in different colors

[Swamp Thing]

TL;DR

A user-defined Mathematica function returns a list (array) of functions. How to plot them in different colors?

If we plot a list of functions in a literal array, they get plotted automatically in different colors, for example:
Plot [{x,x*x,-x},{x,0,10}]

But if we get the list of functions from another user-defined function, they get plotted in a single color:

fnY[x_]:={x, x*x, -x} ... OR ... fnY[x_] := List[x, x*x, -x]

Plot[fnY[x],{x,0,10}]

... even though fnY[x] evaluates to the same array as the literal array in the first example.

Why? How can we apply different colors to an array of functions constructed in a function?

This discussion may help or at least give you some ideas on how to proceed:

Those discussions don't quite address the particular issue I had. After some more searching it turned out that it works if you put a Evaluate[ ] around the set of functions you want to plot.
