Has anyone ever told you that you see the world in black and white?

I do. I usually think simple. I'm white and you black. Does that mean I see only what I want to in the world and that I miss out on the details?
After thinking more deeply, I realized that it's not as simple as I thought.  The world has a spectrum ranging from red to violet.  I should see people as who they are, not what they are.
It's not easy to understand people when I have been wounded, though. I need to forgive them first then I can see the world in many colours.
