Google+'s theme overhaul in Google system

Note how the google system has gone from nice sky-blue to "khaki-black" theme after arrival of plus.

 

I just can not keep myself comparing the red-blue versus black spider-man.

Watch how the black suit gives dark power to spidy.

It's probably me, let hope that there is no evil in going from blue to black (unlike in spiderman movie where spider man becomes evil-istic after going black).
