For some time now I have been wondering about the meaning of:

Parse warning: Suspicious expression after rgb.

There is no reference to any file in which this may happen, nor to the 
suspicious place. I have been browsing different potential issues 
without finding anything /suspicious/.

Any smart idea?

Code analysis: warning due to number of terms in expression not equal to 3.

Lack of file location means that Token.FileHandle is NULL.

seen this before as well, iirc: look for pigment statements that have 
rgb followed a predefined color like Yellow ... effectively it's seeing 
it as pigment { rgb rgb <1,1,0> }

   That warning is the one I most see... due to my tendency to mix 
colors by arithmetic operations (i.e.: Red*.5+Yellow*.3). I learned to 
just ignore it... ;)

LOL that's where I'd seen that before, thanks for the nudge ... perhaps 
my other recollection was incorrect then

I also do that a lot (mixing and... ignoring) ;-)

I just got curious because sometimes it seems not to make sense, 
everything loud an clear, so to speak, but I probably have some hidden 
things I overlook in the process.

Thanks all for the clarification.

Whenever I see that warning, I almost automatically go to section 3.2.1.5.5
"Common Color Pitfalls" in the docs, to 'refresh' my memory of the odd behavior
of dot operators re: colors. If some insight there doesn't solve it, then I
usually ignore it.

BTW, another irritation for me is seeing the warning about 'no pigment type
given' for an object when it's in a lightgroup. That *always* seems to happen
(in v3.6.2), for no apparent reason. Again, I just ignore it.

I'm not sure completelly but I see his warning often when I add a forth or fifth
component to a color vector (e.g. something like this: color Red +
<0,0,0,0.5,0.5>) to get filtered or general transmittance. Mainly within color
maps and the like.

Best regards,
Michael

My solution is like Kenneth's: ignore the warning.
