A while back I purchased three of the sephora prisma chrome Eyeshadows. I purchased them for $3 each.
The colors I purchased were Gold Reflection (yellow gold), Sapphire Shine (described as navy but looks more indigo), and Purple Prisma (purple).
Gold Reflection has excellent color payoff and is true to pan color.
Sapphire Shine was the reason I made my purchase. I thought it would be a true sapphire blue but it goes on as an indigo color. That strange color that when next to a blue it leans purple and when next to a purple it leans blue.
Purple prisma was my least favorite color. It goes on almost sheer and takes some packing on to show up on my skin tone. Maybe I got a dud but if not then I would not recommend this color.
As for swatches I always swatch with no base so that you can make a judgement on the product itself.
