I'll make seven! See the attached zip for blue, red, smoke (on blue), green, amber, stealth (on blue) and crystal (on blue). If anyone wants to make proper smoke and "clear" lenses (for crystal and stealth), then please do. "Clear" is just a white display (but black when pixels are unlit).

Try not to notice that my photographs have perspective while the render did not, thus the knob "sticks out" to the side. Enjoy.
