When accessing the contribution guidance page for an externally translated article that already exists in the target wiki (example), a main action for editing the local version in the target wiki is provided. This action has some clarifying text below that does not follow the spec defined in T212300:
The clarifying text below both actions is shown in grey (Base20, #54595D)
Currently the text is shown in black and it should be shown in the indicated grey.
Note that this particular case is the only exception since the secondary action has the clarifying text in grey, and for the case of articles not existing in the target wiki both primary and secondary action use grey for the clarification.
