An exclamation about something colourful (5)
I believe the answer is:
ochre
'colourful' is the definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
'an exclamation about something' is the wordplay.
'an exclamation' becomes 'och' (I have seen 'Scots exclamation ' mean 'och' so perhaps 'exclamation' could also mean 'och').
'about' shows that the letters should be reversed in order.
'something' becomes 'er' (I've seen this in other clues).
'er' reversed gives 're'.
'och'+'re'='OCHRE'
Can you help me to learn more?
(Other definitions for ochre that I've seen before include "Pale brownish-yellow colour or pigment" , "An orangey pigment" , "yellowy-orange" , "Yellow-orange colour" , "Earth-coloured pigment" .)
