Pigment identification

I have recently been involved in the conservation of a fresco
painting by the Scottish artist William Dyce at Osborne House on the
Isle of Wight. It was painted in 1847. During UV investigation I
found a yellow that fluoresced a strong pinkish-orange colour. I
have not encountered this before and wondered if anyone knew of this
phenomenon and could help me with its identification.
