My Iphone password doesn't work?

Hi, I was on my iphone and it just crashed. It took like 5 minutes to see my screen with the luminosity and all. I tried to enter my password but it doesn't work? And I know it's the right one my screen is like black and white, but not at all. It has lost colors. Yea I know it's so weird I don't know what's happening?

Restart the phone. Best luck.

Reset the phone!
