[2.1] Link colour

[BraveCaperCat]

On the 2.1 version of the docs, some links appear to have gotten coloured blue/green/a different orange for links that go from one section of the docs to another. (e.g. prototype docs to auxiliary docs) I personally don't like this change and would like a way to either revert the colours to the orange that was previously used for all links in the 2.0, 1.1, 1.0 and pre-1.0 versions of the docs.
