Shes actually a real master of colour (A degree in illustration helps) The anti-pink thing is more a reaction to the hideous present day commercial gender mores.
On the "disturbing energy" of some colours, aside from the unnatural dayglo fluorescents this couple of arties actually find it in some purples...which show an "indecision" as to be warm (to the red) nor cool (to the blue). So she never wears purple either...
Pink is itself odd for a different reason as it has no transparency.
