New OC aims to produce colourful design? (6)
I believe the answer is:
mosaic
'colourful design?' is the definition.
'mosaic' can be an answer for 'design?' (I have seen 'Tessellated design ' mean 'mosaic' so perhaps 'design' could also mean 'mosaic'). I'm unsure of the 'colourful' bit.
'new oc aims' is the wordplay.
'new' indicates anagramming the letters.
'oc'+'aims'='ocaims'
'ocaims' anagrammed gives 'MOSAIC'.
'to produce' is the link.
Can you help me to learn more?
(Other definitions for mosaic that I've seen before include "It is pieced together" , "Design of little pieces" , "Design made of small pieces of coloured stone or glass" , "expressed in stones" , "Small square in pattern" .)
