I have officially concluded my modding journey on this workshop.
As always: feel free to make any kind of submods for any of my mods.

Yeah manually recolouring multiple tex files takes a lot of time and effort even if you are passionate about It.
And It's even worse when you have to deal with multiple armour pieces.
Which Is why I often manually recolour unarmoured units or units with light armours.
I did fully recolour some High Elves Spearmen once but It took way longer than I expected, can't picture me doing that for an entire faction.
So It's pretty much a no from me, hope that you can find someone that can help you with that though.
You might want to give a shot to Da Modding Den https://discord.com/invite/sW49MnP maybe you'll find someone who can do that or even teach you how to do that.

Also I apologize, I meant the Warhammer 2 cinematic trailer when the game was first introduced!.

for all dark elf factions*

I mean universally (chest plate and helmet as well as other bits of hard armor). So this would be for by all dark elf factions and wouldn't change color. A great example and my inspiration would be the Warhammer 3 cinematic trailer. The darkshards that ambush the spearmen would be the perfect color.

Thank you so much for listening to my request. I don't have much experience in modding, so if this would take too much effort it doesn't have to be done!

You might want to be more specific on that one.
By "Dark Elves" you mean the main faction or ALL of the Dark Elves factions?
By "Lighter Grey" you mean to literally use a shade of grey or to just bleach a little the vanilla colour schemes?
By "Armor" do you mean the pieces that automatically change colours depending on which faction you are playing or to manually recolour their armour through texture files?

This is incredible! I know this is a bit random, but would you be interested in recoloring the dark elves? I'd love if their armor was a lighter grey as they are slightly too edgy for me.
