Faded - yet it's over coloured! (5)
I believe the answer is:
tired
'faded yet' is the definition.
'tired' can be an answer for 'faded' (thesaurus). I am unsure of the 'yet' bit.
'it's over coloured' is the wordplay.
'over' is a reversal indicator.
'coloured' becomes 'red' (similar in meaning).
'it' in reverse letter order is 'ti'.
'ti'+'red'='TIRED'
Can you help me to learn more?
(Other definitions for tired that I've seen before include "Worn-out" , "Worn out" , "Ready to drop" , "Whacked" , "getting bored" .)
