Setting the fill color on an image in an event does not change the fill color, unless you change another property that forces it to update. Vector display objects do update fill color normally

Hi Ernest,
We saw a bug report for this recently and I believe we are still looking into it; if I can find out any news I will let you know.
Thanks,
Peach :)
