decisions, decisions, decisions...

Although not a big coloured nail varnish wearer, I like to put some on for special occasions. David and I are off to a party tonight so need to chose a colour - these are the 4 choices - I know 1 and 3 (from left) look similar but 1 is lighter and sparklier. 2 is a matt blue/purple. The colours of the dress I am wearing are seen in the background. Help!! *Update* I went for the sparkly blue on the little finger in the end
