Does anyone know if it's possible to change the menu/guide colour scheme? I know my eyes are not that good but whoever set up this scheme had some very strange ideas about readability. The low contrast grey text on dull mauve background is extremely difficult to read from a normal viewing distance. Any help appreciated.

I certainly haven't come across an option to change the colour. Have to agree the guide/menu presentation is awful.

Actually it's a RDR-HXD890 but I would guess the setup is the same.
