RGB matching tool?

[MookJong]

Hi,

Anyone know of a tool (paid or free) that allows you to set a selection of say 10 RGB colours into a palette. Then when your mouse is over an image it will highlight the colours in your pallet if it sees a match where you are hovering over?

Ideally it would not have to be a perfect match but allow you to set a tolerance or an average so you knew the closest colours to those in the image?

Anyone know anything that might fit the bill?

We have a product that can be printed in a number of shades of the same colour. We need to be able to take a clients photo and then look for the closest match.

Before you tell me it depends on lighting of the photo and the sensor of the camera, we have solutions for that part.

Anyone else got any ideas, I have looked into JSColour but my Java script skills are not up to the task of back engineering that.
