Need some help to change kingdom colours through landed titles without editing the original file

[Rhaenuriel]

I realize future updates will most likely bring about bugs if I have a modded 'landed_titles' so I would appreciate if anyone could shine some light on how I should proceed to make a mod that only changes the colour of titles without making too many changes on the original file. Please use some examples if you can, thanks!

You can use the event effect title:TITLEID = {set_color_from_title = title:TITLEID}

Exemple: title:k_england = {set_color_from_title = title:e_mongol_empire}

this will make England the same color as the mongol empire

You don't even have to create a mod for it, you can use the 'effect' console command to execute it directly
