It's red, perhaps, yet means 'go' (6)
I believe the answer is:
stride
'yet means go' is the definition.
I can't judge whether this defines the answer.
'it's red perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'its'+'red'='itsred'
'itsred' with letters rearranged gives 'STRIDE'.
Can you help me to learn more?
(Other definitions for stride that I've seen before include "Move with long steps" , "Long decisive step" , "jazz piano-playing" , "A lengthy step" , "Take a long step" .)
