Hi, You can control the colorbar range via the scalar range settings in the mesh options popup window (get this by clicking on the button two to the right of the camera button). Don't forget to press enter after you've typed the value into the box, as if you just click OK it may not register the change. See the fslcourse practical on FIRST for more info on using FSLView with FIRST surfaces.
