These stage lights had me mesmerised at a recent function. They went through various colour sequences, with several swift permutations and combinations that utilised every colour of the rainbow - and then some!
There was swirling fog all across the stage, being blown by fans in every direction. I studied the lights. Then I studied the fog. Then I studied the lights again. Then I studied the fog again. Of all the light sequences and colour combinations that continued to flash, I knew which one would look the most striking.
But the real challenge was not just to wait several minutes until I had the red main light and the three blue lights. The real challenge was to wait until that particular combination of lights appeared when the fog had just the right density.
(Bear in mind this is just a low-resolution image. If you want to see it full size, you can view it here on my Red Bubble site.)
I needed just enough fog across the stage to give me the density that would work best with the blue and right lights. Too much fog and the lights would have been blurred. Too little fog and the lights would not have had the right effect.
I'll leave it to you to judge ...
