Color mangling in Diagramly

gistfile1.txt

1. Create rectangle.
2. Set custom fill color to "4af" (light blue)
3. Create another rectangle.
4. Resize it to be smaller than the first (it will sit in a corner).
5. Set custom fill color on the new rectangle to "f66" (light red)
6. Export as PNG

The generated image will have the two rectangles in the correct dimensions.

The larger rectangle will have a blue that looks darker, more saturated than what I saw in the browser, but that's fine.

The smaller rectangle will have an even darker blue than the larger rectangle, when it should be red. Same thing happens when exporting as JPG. I used Chrome 17 on both Windows 7 and Mac OS X 10.6.
