Hi all,
I had posted on some of the now infamous "what colour is..." topics about blade colours. I trained to be a theatrical lighting engineer at college (attending seminars with West End lighting designers). One of the tricks they used to determine colour in the old days was to use a sealed smoke cabinet. Failing that, they would shine a spotlight through a cloud of smoke to produce a beam.
The number of variables however are unbelievable, just a few include ambient temperature, moisture content in the air, contaminates like dust, through to power supply, temperature of equipment and vitally the lamp filaments etc, even when using isolation techniques.
In the end all colours are "a close approximation" dependent on conditions. Then there's the greatest difference maker, Us, the human element. Artificial standard stage smoke in a still atmosphere would still probably work best as your canvas as it were.
Hope this helps
