Shade that's raised in Beaulieu House (3)
I believe the answer is:
hue
'shade' is the definition.
(both can mean a colour)
'raised in beaulieu house' is the wordplay.
'raised' is a reversal indicator (going up in a down clue).
'in' indicates the answer is hidden within the clue.
'euh' is hidden within 'beaulieu house'.
'euh' in reverse letter order is 'HUE'.
'that's' acts as a link.
(Other definitions for hue that I've seen before include "'Pigment, colour (3)'" , "Cast" , "Shade of colour; Vietnam port" , "Tint, shade" , "Colour or tint" .)
