```David,

I thought your solution was a little strange, because I would not have
guessed that a second pair of wiggly brackets was necessary. What I
found is that the following works:

ImplicitPlot[x^2 + y^2 == 4, {x, -Pi, Pi},
PlotStyle -> {AbsoluteThickness[2], CMYKColor[1, .6, 0, 0]}];

i.e. remove the brackets around x^2 + y^2 == 4, then you don't need the
second set on the PlotStyle.
