This is something you select during "activation" of the mod by FLMM. It is the "HUD-selection, there the - I think - last option "Blue Vanilla".But this will change the whole look of the HUD. After CF 2.0 is fully installed - sry - not a way to change that I know of.You can then only select the look of the cursors in the settings button of the launcher.(Button with the gearwheel)
