B

Used SCNR to remove the excess green color

C

Adjusted levels and increased saturation

D

Alternative color mix

E

Curves adjustment

F

SHO mix, with careful linear fit and background neutralization

G

Reprocessed completely, stacked in PI

H

Adjusted saturation and levels

J

Conservative noise reduction in chrominance and luminance with MMT to produce a smoother image, but tried to keep it from looking too "plasticy".

K

Alternative SHO mix resulting in a more restrained final color combination that's less psychedelic than some of my other attempts
