Thank you (& jr) for the additional information.

I woke up this morning remembering I released R15 of yuqk with the 
crackle cache disabled (a hack). It was done so I would always have 
handy crackle results without bad results due same thread cache 
collisions. Running this version showed no changes in the crackle solid 
color distribution.

I then decided to read my own yuqk release notes... I ran across this 
for R16: "Of note, the dependency the ip_solid option had on the noise 
generators was removed."

(ip_solid being yuqk's new internal pattern keyword for solid)

I've updated the release notes for this change to read:

Of note, the dependency the ip_solid option had on the noise generators 
was removed. This done so the solid values generated are evenly 
distributed between zero and one rather than being a sloppy, 
normalized/Gaussian set of values roughly centered about 0.5.

The color differences are due an intentional change to yuqk that I'd 
forgotten!
