Our thoughts came together
I made a similar mod an hour earlier, ahahah

I like your version

Yeah, I noticed yours just as I was finishing making mine, lol
But I guess the more alternatives, the better

Original are green camo, fit for the forest,
Yours are blue, right for the sea operations.
Mine are gray, fits great with factory's concrete

I still have a few versions, in particular for deserts (it looks especially cool with a red mask), but I'm still thinking about how not to create 10 identical mods, ahahaha

Create 10 duplicate aircraft entities and items, each one only different in color, instead?
And add recipes (paint [aircraft-name] [color]) and ([aircraft-name] - remove paint)?
Will add a ton of clutter to menus though... like 40 to 60 recipes... Might need to create "painting" tab.
Not to mention VRAM to store all those hd animations for each aircraft version.

BTW, I'm interesting what tools / process did you use to make your version?

Yesterday I tried to expand the mask to the entire camouflage, and I got something, i.e. I made the base gray, and the camouflage changes with the help of the color of the transport, but there are a couple of nuances that need to be resolved.

Well, I just basically used photoshop to turn saturation to 0.
Then of course I added some details, like red triangles and gradient mapping, but that's it.
