Quit Euros playing in blue (9)
I believe the answer is:
turquoise
'blue' is the definition.
(I know that turquoise is a type of blue)
'quit euros playing' is the wordplay.
'playing' indicates anagramming the letters.
'quit'+'euros'='quiteuros'
'quiteuros' with letters rearranged gives 'TURQUOISE'.
'in' is the link.
(Other definitions for turquoise that I've seen before include "Shade of blue - gemstone" , "Aquamarine colour" , "Sort of blue" , "Greenish blue; gemstone" , "not quite green" .)
