Ok minor, minor, minor thing but I just noticed that the Google logo on Google.com.hk is slightly different then the normal logo, why! See the O and the L.
What exactly is it that you consider different? All I see (on a millions-of-colors 1280x800px 13" Mac laptop LCD-screen) are minuscule patches of gradients and washed-out colors in some letters that may well be the result of their imperfect rendering when shifted from Google [presumably] electronic design book to [again: presumably] imperfectly color-calibrated screens of target logos' actual makers.
I can see a dark green triangle at the bottom of the L. The yellow O seems to be a bit more red, but it's not that noticeable. To be fair the post did start with "minor, minor, minor thing"
I saw the "triangle, " too. I was just double-checking in this laboriously agooglsynchronous over-the-interconnected-tubes fashion that I am not not seeing anything more peculiar than some minor-minor rendering blemishes ;-))
Maybe just the way the image was saved, slightly differently than the original?
We'll never know, and since it's minor-minor, it's not really an issue to discuss further.
