The previews below show a few changes in color definitions and color assignments.

Far Left: the color defintion for red was changed to a linear gradient and the color definition for yellow was changed to a radial gradient (yellow inside and red outside).

Middle: The yellow gradient was changed from radial to linear.

Far Right: Same color definitions but this time the circle is not stroked (notice the yellow line around the circle in the first two)
