I don't know any way to change the colour of the default locator, but
you can replace the default locators with anything you like using the
Appearance option of LocatorPane:
Manipulate[
LocatorPane[pts; Dynamic@pts,
Dynamic@Graphics[{Spline[pts, Bezier]}, Axes -> True,
AxesLabel -> {x, y}, PlotRange -> {{-3, 3}, {-3, 3}},
Background -> LightOrange],
Appearance -> (Graphics[{#, Disk[]}, ImageSize -> 15] &) /@ {Blue,
Red, Green, Brown}], {{pts, {{0, 0}, {0, 2}, {2, 0}, {2,
2}}}, {-3, -3}, {3, 3}, ControlType -> None},
SaveDefinitions -> True, Initialization :> {Needs["Splines`"]},
AutorunSequencing -> {2}]
