Just go back to MS Paint; you're not ready for Photoshop -_-
I use photoshop all the time. MS Pain doesn't have a pallete that you set it ALL to what you want -_-
__________________ Oh squiggly line in my eye fluid. I see you lurking there on the peripheral of my vision.
But when I try to look at you, you scurry away.
Are you shy, squiggly line?
Why only when I ignore you, do you return to the center of my eye?
Oh, squiggly line, it's alright, you are forgiven.
