Layer on article turned to shade of red (5)
I believe the answer is:
henna
'shade of red' is the definition.
'henna' can be an answer for 'red' (I've seen this before). I am not certain of the 'shade of' bit.
'layer on article turned' is the wordplay.
'layer' becomes 'hen' (something which lays - eggs in this case).
'on' says to put letters next to each other.
'article' becomes 'an' (indefinite article).
'turned' is a reversal indicator.
'an' in reverse letter order is 'na'.
'hen'+'na'='HENNA'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for henna that I've seen before include "Cosmetic plant dye" , "Red-brown dye used for body decorations" , "Red-brown plant dye" , "Shrub used for cosmetic colouring" , "Reddish brown dye used on hair" .)
