IMHO...
I never really understood the "clash" concern between caliper and interior colors, since they're not really in the same view at the same time. That's like saying your basement color clashes with your upstairs office color.
I like the look of red calipers, but I think the blues work great with San Marino as well (see link below). Blacks are fine but they tend to get lost in the wheels, so if you're just trying not to draw any attention to them, that certainly works.
