Make another picture using red, green or blue? (6)
I believe the answer is:
redraw
'make another picture using red green or blue?' is the definition.
I can't judge whether this definition defines the answer.
'red green or blue?' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'red' is 'edr' which is present in the answer.
'green' could be 'raw' (both can mean naive or inexperienced) and 'raw' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for redraw that I've seen before include "plan afresh" , "Find a new winner" , "Change" , "Sketch again" , "Adjust" .)
