Hello Brian Workman,
With the Q1.2010 release we introduced a major facelift for all 6 built-in themes in order to deliver a more consistent look and feel throughout the whole Silverlight suite. The decision is based on feedback concerning inconsistencies in the visual appearance amongst the different controls.
In the new Summer theme our gauges are blue to achieve visual consistency. We hope that you are satisfied with the new look of our Summer theme.
Feel free to bring any concerns you might have to our attention.
