Error in point to color calculation

[FokkeZB]

I was creating an Alloy widget based on your initial calculations when I noticed an error. They are even visible in the screenshots in your read me. Clearly the green of the background does not match the color where the cursor is.

You can find my calculations at the following URL, but please note that I added a grayscale area to the image so you can't use them 1-1:
