Personally, I favor the "in-between" approach. Make the no-shoot markings dark-on-dark (i.e. impossible to see without a flashlight), then let people solve it as they see fit. If they choose not to use a flashlight, any speed advantage they save is more than offset by the increased probability of hitting a no-shoot.
