Script to cycle through colors in a picture

[schwooba]

n00b here. I have a background image in my CSS style sheet that I want
to slowly fade through a couple of colors on my website. Can javascript
selectively choose only one of the colors in the picture? Can this
even be done? Thanks!

no there is no way (without using server scripts like php) to get the
color in an image. a workaround could be a solution with xmlhttprequest
- a php scripts gets the colour and a js script uses the result.

Why use an xml http request? The colors of the image will not change in
real time so if a server side scripting facility exists it could insert
the information directly into the web page and have it available form
the outset. Though I don't see how "use the result" is supposed to work.
