Try changing the colour from 'auto' to 'blue'.

Also... after you apply the auto differance key... you have to turn it on since it's not activated by default. You should see a little red dot, click on the red dot and it should turn green telling you that the key is activated.

Is that something different in VisionLab? I know in CompositeLab that I have to turn on Chroma Key after picking my color, but when I use auto difference, it's always on by default.

Yeah, just a bit of confusion, I think. Its the same in VisionLab; the Auto Color Difference Key is turned on by default. The Chroma Key is turned off by default, to allow you to more easily select the color in your frame that you want keyed.

If the spill suppression isn't removing all of the blue that you want to get rid of, you can try experimenting with different combinations of other key filters such as contrast, Gaussian blur, and erode white to see if it helps make the remaining blue less noticeable.
