One tip: You might find that it's easier to wiggle the hue value in HSL than to wiggle channels in RGB if you're trying to "wiggle between different shades of red". Other than that, you just wiggle color like any other multi-dimensional property, like Position.

This should give you some ideas. Set your color to a mid red (r = 127). Then use a wiggle expression like this:
w = wiggle(3,.5);
[w[0],value[1],value[2],value[3]]
That should move it around quite a bit. In expressions, color channels are values between 0 and 1, so if you set the red channel in the middle (.5) and then wiggle it up and down .5, you get the full range of reds. If what you really want is reds with small amounts of blue and green, that's a different story...
