Marissa,
So, I can't tell you it won't take the colours away, it might. I personally hated Prozac (I've been on four or five different meds and it was my least favourite xD) but you might like it. Give it a chance. And the changes won't be lies, if they happen they will be real. Medication is always hard, it works differently for everyone, but just try it. Be open to it, it will be alright.
