As for color vs colour, it depends on your accent. In my Northern English twang, the word is pronounced similar to "cullah" (with the "ull" as in "bull"), so whilst the English spelling just about fits, the "or" in US English just seems wrong. Imported Japanese TVs and VCRs used to confuse and irritate me as a small child with their "incorrect" spelling of colour (especially as I was reminded of the UK spelling before each programme in the 70s as each station proudly proclaimed their colourness in huge letters before each programme, thus:
... before I understood the differences between US and UK English. I still think it was lazy of Sony etc not to bother replacing the sticker on the front of the TV
(And yes, the North-East accent can be a bit harsh at times
