colour playing

I just found this, from a link on Pinterest. I really do learn so much from Pinterest - don't you!!

How to generate your own colour palette from an image. I don't use photoshop - but if you do, then you probably already know how to do this is. If you don't - then visit here for the tutorial, then here to get to the color palette generator.
So much fun. I'm addicted already. I have seen these around the web, but never knew how to do it. Yah!
{The image does have to be online - but all my good ones are mostly on flickr or my blog or instagram(search petalplum) anyway - so that's no worry for me.....}.
