High Visibility Mechanized Badassery

In the future, if we have giant mechs like this one from kwi-chang roaming the battlefield, you can be sure that the ones that are brightly colored were built to kick some serious butt. There is something to be said for camouflage, it keeps you somewhat hidden until you're ready to fight. But then again if you're a twelve stories tall heavily armed bipedal mech, there's really no place to "blend in".
