Who owns orange?

Last week I saw the advertisements for Tangerine (An online bank) and Langara College (A public post-secondary institution) next to one another at a SkyTrain station. The same day I also saw the TNT delivery van.

All three of these firms use orange as their signature color. (And essentially the same shade of orange as Home Depot.)

In other categories there are often multiple organizations that use the same colour. (I've lost count of the firms that use red.) But these four organizations all operate in different industries and so the issues around colour identification and confusion are pretty limited.

I wonder who else will attempt to adopt orange as their signature shade?
