Hi LittleOurkie.
Yes, I think youīre right about that. But to the eye, they look more orangeish. I believe that the light they emit is quite monochromatic (apparently thatīs common in street lighting), so itīs difficult to get any kind of colour spectrum from (that wich is lit up by) them. But you can also see that the more common (the shops & buildings) fluorescent lights looks green. (Wich it usualy does, in fact. Albeit somewhat less saturated) ;-)
-But I actually think that it looks rather cool :-D
