Like the coloured end (3)
I believe the answer is:
red
'like the coloured end' is the definition.
I can't tell whether this definition defines the answer.
'like the coloured end' is the wordplay.
'like' becomes 're' (I can't explain this - if you can you should give a lot more credence to this answer).
'end' indicates one should take the final letters.
The final letter of 'coloured' is 'd'.
're'+'d'='RED'
Can you help me to learn more?
(Other definitions for red that I've seen before include "14 -- breed of 4" , "- - poker: Kniphofia" , "'If you see it, perhaps you're angry (3)'" , "Warning light colour" , "Blushing" .)
