Ok folks,
I usually give a run down of all the clues but tonight I haven't got the time. Plenty of intricate and crafty wordplays which I do like, however, tonight I'm going for a more straightforward wordplay as the answer of 'Stroop Effect' isn't the most common of knowledge.
So the winner this week is jws with:
Swear black is white with colourful language
I did like the use of 'swear' with 'colourful language' for the surface read. Hard luck to BBM2 for his post at 19 which had a similar spin.
Here is your prize jws.
