Companies are very very very specific about their logos, how they are to be used, what backgrounds they can have. It's not unusual for their to be a branding "bible" thats hundreds of pages. Why does this matter? Because the background is on white. They're going to require that if the logo design looks best on white, that there must be white.

So all you've done here in introduced ANOTHER color to be printed in a lot of cases. Ok, it works fine on a Starbucks cup and on a webpage... but in most real life cases? Way way more complicated. The McDonald's Arches are prominently lit on the front of their buildings. Now instead of one lighting loop, there needs to be two.

And while I do like the design of some of these logos, like Coke. The Apple logo is TERRIBLE. Some logo's this High School design class of "lets make some of the logo white", just doesn't work.
