Happy to shade again. It was too bright (6)
I believe the answer is:
glared
'was too bright' is the definition.
(I've seen this before)
'happy to shade again it' is the wordplay.
I cannot really understand how this works, but
'shade' could be 'red' (red is a colour or shade) and 'red' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for glared that I've seen before include "Was too bright" , "Glowered" , "Stared fiercely" , "Looked angrily" , "Lowered" .)
