Of course, on a CRT monitor, purple & yellow does not make white. This link from the post's comments explains:
lagom.nl/lcd-test/subpixel.php

This subpixel rendering probably works for the most common monitors out there but for some it'll look discolored and strange. Problems also come up when the favicon size increases for any reason.

Shame too. I'm sure the guys at YouTube would gladly take the suggestion if not for the drawbacks.

The new one looks much better on my LCD.

I think it's pretty obvious that by comparing the 2 expanded versions, that making some simple adjustments to the original one would result in a much clearer favicon.

You don't need sub-pixel rendering, just a little common sense to make it clearer.

That's pretty clever, gonna look into subpixel rendering now.

I never looked at the Youtube favicon that much, but when you look to it, it is a really 'bad' reading icon. The right one is much more clearer (LCD).

I do not have a CRT anymore, too look have its looking there. But for 95% it would be a big improvement. And about stretching the icon, that is a true, but mostly (90% ? or more) its not stretched. That depends on the users browser and setting in there.

The subpixel one looks *much* clearer to me (though it's using another pixel in width which could have made the b much clearer anyway)

gdi++ is much better than cleartype

I agree with Paul. The purple and yellow don't seem to be making much of a difference, to me at least:

I have to agree with Paul and Waldir. Exactly my thought.

The purple and yellow help with the anti-aliasing of the text, thatats about it. If you look at your version versus the original, you'll see that you're loses definition around the b's and the u's.

Err, yours versus the one with purple and yellow sorry.

I'm seeing a new YouTube icon now, they've got rid of the top-right highlight, sharpened the corners, anti-aliased the black You, and pixel-aligned Tube youtube.com/favicon.ico

They changed the favicon:

They didn't go for the yellow "Tube" though, perhaps a good choice.
