my guess is that you are thinking of a centrally located logo where the current words are, while the design is for the entire header bar, which is a little cheeky on my part D
good point though, the intention was [and this is where the rgb stuff came in] to match the green of the site in the vertical line that sits behind the 't' of ot.
best thing to do is define how you see the logo working [central at the top or entire header, repeated at other parts of the site, that sort of stuff]
