I've always loved that bright blue, somewhat purplish, hue we call International Klein Blue after the artist who formulated the colour and than painted vast canvases of it.
IKB was developed by Yves Klein and chemists to have the same color brightness and intensity as dry pigments, which it achieves by suspending dry pigment in a clear synthetic resin. This new medium was patented by Klein. This top from Chris Benz reminded me of the hue. It would be the perfect thing to wear to an Yves Klein exhibit. Or just in general.
