This photo is a crop from a 1:1 photo taken with the Sigma 105mm F2.8 DG DN MACRO | A and a Sony a6600, at ƒ5/6. The fluff looks partly whiteish and partly with a cyan cast. The butterfly is a Melanargia galathea and, looking at the specimen images in Wikimedia, I don't see any cyan hue, so I suppose it's a kind of fringing. Can you confirm? It seems no tool in Capture One is able to remove it.

Note that the intensity of the cyan cast is a bit reduced in the attachment as an effect of JPEG compression.
