Leap about without colour (4)
I believe the answer is:
pale
'colour' is the definition.
(I know that pale is a type of colour)
'leap about without' is the wordplay.
'leap' anagrams to 'PALE'.
But, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for pale that I've seen before include "It's unacceptable to go beyond this" , "Light in colour" , "Dim - wan" , "beyond which one is out of line?" , "White" .)
