As with all cosmetics, buying the right nail polish for your hands or feet can sometimes be a tricky business.

What looks good on your friend or some celebrity you saw in a magazine may not necessarily suit your skin tone, natural colouring and more.

I stumbled across the OPI Nail Studio, which is basically an online simulator to give you an idea of what shade of OPI nail polish is right for you. OPI is pretty much my favourite nail polish brand - there’s a huge range of colours and the price is reasonable - you’ll usually pick up a bottle for around $20.

You can set your skin tone and nail length then test out the different shades from the various collections to see how they’ll look on you. I’ve decided I like the look of the Go on Green colour (pictured here on my approximate skin tone and nail length).

I’d love to see OPI develop a tool like this for feet too - not because I desperately need it to make an informed decision but because I’ve had fun playing with the hand generator for the last half hour and need more entertainment.

You’ll also find OPI’s Australian stockists at the site.
