I understand this, but small changes to colours probably wont be accepted considering the ST is presumably already almost done working on the NGP

I'd assume judging by how they pushed code Yesterday, WWW is still going to be used after NGP. I am going to refactor this PR to include any left over orange to turn red or red dark so it's a meaningful change.

They change a lot. But, hopefully ST notices this change.
