The turquiose color rendition is similar to the green and blue. Still no where near as good as white but maybe a little better than red. For night vision I actually chose the orange Photon. I know, not nearly as good as red for nighvision preservation, but still not as distrubing as yellow. For me, its a good compromise. As far as using any blue/green light for night vision, from what I understand those are the worst colors to use considering our eyes are most sensitive to light from the blue/green end of the color sprectrum. Anyway, proper colors of red (I think below 600nm) are the best choice for not disturbing your night adapted eyes.
