I don't have Octave 3.2.3 available to run, but you try ...

h = errorbar (x, y1, dy1, x, y2, dy2);
set (h(1), "color", [0 0 1])
set (h(2), "color", [1 0 0])

... to change the color to blue for y1 and red for y2.

Does that work for you?

If not, what does the follow give you?

        get (h, "type")
