If there is NO light shining on your texture, it will look very dark 
with the default ambient of 0.1.
This is a glowing finish. If you use that in a radiosity scene, it will 
shed a light green light on everything around it.
It can easily get oversaturated if there is also a light shining on it. 
The default ambient is 0.6. With a light of intensity 1, it will combine 
with the ambient to potentialy give you a brightness of 0.6 + 0.8 = 1.4 
and a resulting colour of <146,218,164>/255 * 1.4
<0.5725, 0.8549, 0.6431>*1.4 = <0.8015, 1.1969, 0.9003> that get clipped 
to: <0.8015, 1.0000, 0.9003>
Not the same tint, the saturation is diminished.

Defining rgbf with a 3 component colour is legal if unusual. The filter 
value is then set to zero.
Defining a colour this way is also legal:

rgb<Red_value, Green_value, Blue_value, Filter_value, Transmit_value>

and the filter and transmit values WILL be used. (found that by accident)
