What if one creates images in ToasterPaint and then uses them as
backgrounds in Lightwave (As I frequently do.)If they are too hot in
TPaint wouldn't they be the same in Lwave?
I often have clients who insist that their logos be exactly the same
colour values that they give me even if I suggest that they may not
work in video as they would in print, then when I do that they
complain that the colours are too hot. (These are usually objects
where the colour values are set in Lightwave.)

Sounds like good advice. If I set an object at r:200 g:0 and b:0 and
then make it luminescent and add a lot of bright lights to the scene,
wouldn't part or most of the objects colour values increase over
200? I have done animations with objects that I think are "safe" in
their colours and then loaded them into Tpaint, and checked certain
pixels and found that their saturation is much too high. (I think
so. I may be wrong on that though.) If this is true, what is the
solution other than batch processing all the files through a filter?
I know someone else mentioned my next point and the answer was : "
they shouldn't have to" but If an editor calls me and tells me that
the colours are too hot or are bleeding and I think I have taken
every precaution to avoid that, why can't they lower the chroma
level on their TBC? The only answer I have gotten is that it would
change the colour of the logo, which I would think would be the
same if I lowered the saturation before I render.

P.S: The comment I hear most after clients/producers view my
preview tapes: "that's great but let's make the red even brighter
and more vibrant"
