Expanded Colours

4.0.* Compatible

This mod augments the vanilla palette to a total of 195 colours in various ranges.
Additionally, all the new colours are usable by the AI.

This mod is savegame, achievement, ironman, and multiplayer compatible

It can be used in multiplayer even if other players do not have it, but players without the mod will see the added colours as black. Vanilla colours are included, so any flags using them will show up normally.

This mod should be compatible with other mods and Stellaris updates as long as the flag creation interface or the colour files aren't modified / updated.
If you have problems with this mod, try disabling all your other mods first, just in case there is a conflict.

In contrast to the previous version, these colours have been picked strategically.
Firstly, all colours were chosen in OKLab colour space, to ensure that the resulting colours cover the perceptual space efficiently. Secondly, I've filled the grid in groups, to further control the coverage. These groups include the vanilla colours, instead of separating them as their own group.
Starting from the top:

• Pastel colours (3 rows)
  
• Bright colours (4 rows)
  
• Vibrant colours (1 row)
  
• Dark colours (3 rows)
  
• Pale colours (2 rows)
  
• Misc colours (1 row)
  
• Grayscale (1 row)

Randomizable combos were created such that the colour pairs have a minimum perceptual distance to avoid monochromatic flags, but otherwise they are fully random.
