I got these nice and cheap from eBay, they seem to be more expensive in New Look and also they never seem to have any colours other than neon orange and green.
The photo without the flash is a much better representation of the colours.
105 - Midnight Blue - Not quite, more of a shimmery mid to dark blue
157 - Vampire Purple - A shimmery lilic colour, quite sheer needs 3 coats
142 - Deep Purple - Really nice purple, I'd describe it as darkish purple!
161 - Aubergine Glitter - Have to agree with this name, its got a fine gold glitter throughout
