[SOLVED] Bash changes consolle's colors by itself

Question

Hi archers,
I've wrote a little script which ask for the result of a given random moltiplication because I was exercising with $RANDOM and something strange's happend.
No matter where I am (Tty, Tmux, Urxvt, Xterm...) Bash changes consolle's colors by itself if I do ^c to stop the script, instead of write a reply.
i.e.'s:
correct behaviour
$ 8 * 9 = ?
$ 72
$ ls
file in red file in yellow file in grey...
Wrong behaviour
$ 8 *9 = ?
$ ^c
$ ls
file in blue file in green file in white...
What the heck?
Bash version is 4.2.39(2)-release.
The script is the following:
while :
do
min="3"
max="7"
fat1="$(($RANDOM%$max+$min))"
fat2="$(($RANDOM%$max+$min))"
prod="$(($fat1*$fat2))"
echo "$fat1 * $fat2 = ?"
read res
while [ "$res" != "$prod" ]
do
echo "$prod"
echo "Insert the correct result."
tavPit
done
return 0
done
Everything is up to date.

Here colors change when I send SIGINT to a running instance of my script; as said before.

Whole.

That's why I'm asking.
Bandit Bowman wrote:[...] here's a slightly more straightforward version [...]
Thanks, I've learnt something.
Bandit Bowman wrote:[...] although it won't help with the colours.
Thanks for the reply anyway.

Also, many thanks again.
Edit: solved. "$LS_COLORS" must be set if you want colors.
