Anti-phishing feature

Some phishing pages pretent to be a MetaMask. I think an idea is to add a feature in MetaMask that changes the orange fox on the unlock page to a random user seed based colored animal. Or some background that is special to the user. The hacker can not access the image and can not represent it in the fishing page and the user will figure the hacker out much easier.

For someone who is not very security conscious, no matter how many layers of security you put in place, he will screw it up.
