Certain leaks are pointing to the possibility of seeing the Nexus 5 smartphone in various colours aside from the standard black and white variants. Rumour has it that we'll see Nexus 5's in red, blue, yellow and green. While there's not telling if this is a hoax or a way to further entice new users into the Nexus fold, using Googly colours is a strategy Google currently employs for it's most recent HP Chromebook 11 models (although certain colours, it seems, are not available in all markets). Stay tuned for developments.
