Dear Greg,
I'm just looking at the new mapping of the falsecolor scale in RADIANCE 3.8:

I makes me wonder where you got the inspirations for those bizzare lines
from. Hope you're not taking any illegal substances?

Hi Axel,
It's a fair question. I was inspired during last year's attendance of the Color Imaging Conference, where I find myself again this year. It occurred to me that the original scale in false color didn't actually traverse that many "named colors," making it more difficult than it needed to be to differentiate values. Having seen a number of color scales, including spectral scales like the original one I used and thermal scales, I decided that some mix of the two might work better. So, I essentially chose colors from a palette moving through the cooler spectral colors, then shifting to a thermal scale in the green-to-red (which became a green-to-brown) transition. This then continues on through red and orange to yellow, avoiding white at the end as I found it to be confusing. I can't say the results are terribly aesthetic, and the images look a bit bloody in some cases, but it is much easier to pick values off the resulting scale.
The curves you plotted are simply a result of interpolating the colors I chose along the way. I made some effort and went through numerous iterations to balance out the perceptual movement in an attempt to keep the scale uniform, again with debatable success.
