256			Total number of levels (i.e. 0:255 has 256 levels)
1	-1		Model 0:RGB, 1:Lab; 1:mimic RGB spin & phase in Lab, -1: Lab s&p in RGB
---- Saturation & Gamma
1.5	2		Saturation, force maxsat (0:off, 1:on, 2:min(sat,max), 3:maxsat times sat)
0.8	1.	1.	gray gamma, rotation gamma, amp power
0.30	0.59	0.11  	RGB-to-gray weights
