[SML] Gel history

[Steven Backus]

Using my google-fu:

https://www.controlbooth.com/threads/odd-gel-names.9981/

which says:

As to Surprise Pink, it also has to do with the fact that it can
appear warm or cool, depending on the color it's paired with.
Think about the effects of using two different systems, one with
R33 and R51, and the other with R60 and R51. In each system, which
color is the cool, and which is the warm?
