Colour challenge: Brimstone on Dandelion

This is by far the yellowest photo I have, you may want to put on sunglasses.

It is a brimstone (Gonepteryx rhamni) on a dandelion:

Nothing subtle about it! Photographically, it is nicer to set these butterflies off against their complementary colours, like this:

Male brimstone:

Female brimstone:

^{Olympus XZ-1, 112mm, ISO100, f5.6, 1/400s}

But it is Yellow Wednesday, so the yellowest one has it!
