when I looked at the cinemaquestinc.com site, I did not notice a lumen number on standard info sheet
That's correct. I've never considered it necessary since there are likely so few consumers who could interpret lumen figures effectively in a bias lighting application.
I thought a quick google on the name would provide the color sample. If you have a monitor that is color calibrated---and I presumed you did---this is trivially easy and instant.
Frankly, I've never even thought of Googling a paint reference. Thanks for the tip. My laptop screen has limited calibration facilities but the image would be close enough for this purpose. If this was so "trivially easy" it would have been appropriate and duly considerate for you to have supplied the link from the start, don't you agree? The sample on my screen appears to have some red in it, as well as yellow, therefore, a simple blue filter wouldn't offer adequate color correction. There would also have to be a cyan component to counter the red.
Because I did not expect individual advice, I had just hoped that there would be a temperature range on the Wall paint color for which you would recommend your product, and beyond which you would recommend one look for alternative solutions.
What you had hoped for is not really practical. That which I recommended is still my best advice. I don't catalog other lighting supplier's solutions. The encounters I've commented on in this thread are only a few of those products that claimed to offer the right color but thus far have proven to be substantially in error. It's a chore for me to maintain products that do it correctly. If forum members want to locate alternate solutions, at least they can follow my explanations of the principles involved to achieve correct results.
