OPI - Purple with a Purpose

This is OPI - Purple with a Purpose. A gorgeous colour and I love it, shame my camera did not capture the colour correctly??Taken with my Pentax Optio camera, that I use for my nail photography, the colour does not come out as is?? What do I have to change on settings to make it right?These two photo's were taken with my mini-corder and the colour is as true to life as can be.
