not sure what the goal is but you can view/edit/save your transformation experiments if you click "open options"
you can copy paste your specific changes there
the cols logic is the following:
x: [y,z]
x = start of the block in original pallete
y = start of the block in new pallete
z = blocksize
here is a keep colors "the same" example
- name: copy(ufo-battlescape)
op: transform
pal: ufo-battlescape
maketrans: false
cols:
0: [0, 16]
16: [32, 16]
32: [96, 16]
48: [48, 16]
64: [64, 16]
80: [80, 16]
96: [96, 16]
112: [112, 16]
128: [128, 16]
144: [144, 16]
160: [160, 16]
176: [176, 16]
192: [192, 16]
208: [208, 16]
224: [224, 16]
240: [240, 16]
