__ tone (5)
'tone' is the definition.
(I know that tone can be written as shade)
This is the entire clue.
(Other definitions for shade that I've seen before include "Colour; slight amount" , "Area sheltered from the sun" , "Partial or comparative darkness" , "Quality of colour" , "Colour; protection from sun" .)
(Other definitions for earth that I've seen before include "hideaway" , "Land" , "Terrestrial sphere" , "It is necessary to clear" , "wire" .)
