Hi Tzar Sasha,
Not once has the colors been mixed up and all of your original color stars are available for use. If you'd like I can send you the star sea tile set for you to look at and test with.
Yes, I'm very interested in what you made

could you send your sea.pcx in a pm to me ?
I do think that the ocean tiles are like the land tiles. If you follow the exact pattern of the land tiles I'm pretty sure that you can have larger nebula than just the corners of 4 squares. I'll play with that a little to after I've finished up the terrain for the Stargate mod.
Sure, that's what I wanted to show with the big screen above.
Perhaps we should use sea instead of ocean.
The game can be set up with coast to ocean without sea. So occasional sea spots as nebula would make sense.
Why should sea be the better way? I worry about the AI behavior, allowed to "sail" with ships through ocean but not through sea ...
And is there a difference to have occasional sea spots instead of ocean spots ?
BTW for the Stargate mod I'm using your star pattern in the ocean and coast. I don't know if they want stars in their space or not cause they want to have planets that are at least 3x3 you know normal civ terrain.
Is there already a terrain for the Stargate mod ? So it's possible to create a multi-tiles planet, see
here
you see, that it's possible to create 4 tiled planets (left top), or 12 tiled planets, as big as a cityrange (right bottom).
You just have to change the coastline-tiles so that those planets become circle.
with different landterrain (coastlines) it's also possible to create small desert planets (one tile) and big green planets (4 or 12 tiles)
Or you take a different terrainset, like the one, they used for the StarWars Mod :

It's somewhere here in the Graphics Modpacks Area
