I do not decide anything. This is my assumption,
because it was never the case over the past years.
In reverse, who are you to decide if it is acceptable?
Yes, you are right. Only moderators can decide if it can be accepted.
But where will you draw the line if you accept one recolor of one user and deny one recolor of another user.
What I could observe over the past years was this simple decision making
which might be the fairest one in my opinion (no cnp / no recolor).
But it does not hinder exceptions like this

if a certain artistic level is achieved.
