Vehicle Color Expander
This mod allows to have more than 4 colors variations per vehicle model.
The full XML use instructions are at GitHub repository[github.com]
The Basics
This mod will read XMLs from two sources: asset folders and a folder created under Cities Skylines’ AppData folder.
The first one must be used by asset makers to allow setting configurations for their creations. The second option can be used by the player to configure defaults for the game, also adding some configuration for an asset (from base game or workshop).
Pastel Colors generation
One of options is the pastel colors generator. This will allow to always generate a cool color in each building without declaring them all. There are some options to define the color saturation rate and which kind of color shall be allowed or denied. Example: use AVOID_REDS or AVOID_BLUES if you think the color genaration is too pinky.
Color List
You can also set a list of allowed colors if you choose for that. No color list length limit is set, so use it to balance the probability of each color repeating them on the list to make them appear more often.
Enjoy!
