color selector

[drifter]

I want to create a color selector from an image. Basically I want people upload a logo. I want to put something that I can select colors off of that.

I know I can use HTML custom cursors to make an eye dropper. I know I can use the input type image to get x and y coords. but how is there a way using GD or something to get the color of an spot of an image and return the RGB?

Also, does anyone know where a script like this might be so I can avoid reinventing the wheel if possible?

Thanks

This would go in a javascript help forum.  PHP works on a server-side basis meaning once it's processed and outputted there's nothing left for it to do.  You would need a client-side language such as javascript to accomplish this.  Take a look around google see what comes up.

I know how to make a color selector in javascript  - I am looking to make one where people can upload an image and I use an input type image to get an X,Y and then I want to get the color of that point.

I did find imagecolorat() just now.

My other question that I can not find an awnser to is if I can take an image and return the top 3 most used colors in the image???
