Fwiw, changing ther colors of many logos violates various rules. I think both apple and Ms don't allow their logos to be altered, not even ther colors.

Displaying logos can be tricky, and it's scary when wealthy companies send legal complaints about their logos.

Edit; phone added odd words.

I've tried to link to the official guidelines (and have an "-official" version).

I prefer not to mess with the logos other than to make them fit.

Hopefully companies that care enough to send legal threats will care enough to have a nice looking version to begin with, and I won't need to mess with it at all.

And I'm happy to take submissions from official sources!

Yes they have the stuff in their terms but chill. They have never sued anybody for putting a monochrome logo in their client list, except they had others teason to sue.

Aligning all logos on eg a client list re color and hue is normal and tolerated.

What you should not do is to mod learned GUI elements like sign-in buttons, eg FB Connect.

Yep, here's an example from Facebook:

> Don’t modify the "f" logo in any way, such as by changing the design, scale or color. If you can’t use the correct color due to technical limitations, use black and white
