Trying to display a character on top of my maze

I'm creating a maze game for a project at my university. It's a maze game and I want the character to detect if a color near them is black and if they are moving in that direction they will stop moving in that direction. Basically I'm trying to do collision detection with color. When I try to display my Player character it just displays a grayish screen. I'm not sure exactly why my code isn't displaying the character. I have a file "hero.png" in the same folder as my .pde. Any suggestions?
