Henry’s first English Queen picked up something of a colourful character (5)
I believe the answer is:
henna
'something of a colourful character' is the definition.
I can't tell whether this defines the answer.
'henry's first english queen picked up' is the wordplay.
'henry's first' becomes 'h' (1st letter of 'henry').
'english queen' becomes 'anne' (I've seen this before).
'picked up' says the letters should be written backwards.
'anne' in reverse letter order is 'enna'.
'h'+'enna'='HENNA'
Can you help me to learn more?
(Other definitions for henna that I've seen before include "Reddish-brown hair-dye" , "Red-brown plant dye" , "natural colour?" , "(Shrub producing) reddish dyestuff" , "hair colour?" .)
