Here I have done a comparison swatch of some of my holographic polishes. I class these ones as the 'golds', compared to the 'browns' and 'beiges' of future comparison swatches.
This first pic was in the sun and shows from left right:
Index - Art Form - Gold
Middle - China Glaze - GR8
Ring - OPI DS Classic
Pinky - China Glaze - It's my turn
Here are the same indoors.
Art Form Gold is really more a platinum colour and GR8 is the only real yellow gold. 'It's my turn' is slightly more yellow than DS Original which can just be seen in these pics.
I can't pick a favourite amogst these, but I could probably say that my least favourite is GR8, only because I prefer a less yellow gold polish.
