I set about testing these paints, on Arches watercolour paper (300gsm) as well as on Yupo paper. When I received paints, I was most impressed firstly by the personal attention to detail: from the packaging, labelling and branding, hand written note on colour card from the creator, even detail to having little magnets affixed to the palettes to keep them attached to metal container!īeing a bit of a magpie, I was naturally drawn to the shimmer/iridescence of these paints.
