In what looks like a fan-made video, five Lumia 800 handsets are shown. Three of those are existing colours and two with new colours; one red and one green. The white one seems to be missing.
The possibilities are endless, but it seems that the new colours are only cases as the keys on all are black. Surely Nokia will attempt to appeal to a wider audience by adding more colours as they go along, but cases will be an easy way to add even more colours. White, Magenta and Cyan are primary pigment colours, Yellow too. Rumours have suggested that a yellow version is in the making.
The Nokia N8 came in seven colours (Silver, Black, Green, Orange, Blue, Pink and Bronze), two of those colours only launched several months after the initial release, so Nokia doing the same this time is plausible. Only time will certainly tell.
