In that image i think i had the brightness and contrast up a bit so colors look a little washed out, the green tint you speak of is prob a combination of the game and the bulb. The bulb im using is a 400w MH with a kelvin rating of 6,500 which is a white spectrum ( close to the kelvin of the sun ) but it only has about 10hrs of use on it and the spec's of these bulbs are rated after 100 or 1,000 hours of use, so it's common for the color spectrum to be off a bit until the bulb gets broken in.
I finally hooked my PC up to it and im fairly pleased, still lots of tweaking to do to get the best image i can for example my spherical reflector is about 8-10mm off center (reports using a lux meter has shown it improves the brightness up to 25%) if positioned properly, i have blurred left and right edges, slightly darker corners, bulb isn't center to the rear fresnel lens, etc... What to mention here is that 25% increase is not as much as you think but it's still a significant increase, these DIY projectors only transmit about 5-10% of the light source you have compared to commercial projectors which have a higher percentage of transmitted light (i believe it's around the 50-70% range).
As to your question fluff as of right now before further tweaking i can have a 15w compact florescent with lampshade on and i am still able to manage a fairly usable image, i would assume with perfect adjustments i could have a 15w CF without lampshade on and be able to use it perfectly fine. Of course there are other ways to get a brighter image, such as a pre-condenser lens, higher wattage bulb or atleast one with a smaller arch as the rear fresnel lens works to take a point light source and transmit it as evenly as possible across a larger area, so the bulb i have now is probably only using 15% or so of the arc. As soon as i feel like messing with my cameras settings i'll take some better pictures and also some with the lights on.
Hope some day soon to jump on CS using the projector to see what the experience is like.
