Good question.

I think the first thing is to decide if you write your pages in English (UK) or US (USA) and keep to it. But with a few "colour (US: color)" examples here and there in the body text. Then define your language with either;
<META HTTP-EQUIV="Content-Language" CONTENT="en-US">
<META HTTP-EQUIV="Content-Language" CONTENT="en-GB">

I do not know if they intended it, but Google seem to rank sites I have done like this equally well for both variations.
