It would appear so. It seems that the overriding works differently than I thought. Simple fix would be just adding HRE to Alternate Color's landed_titles file.
If you don't know how to do that add me and I'll tell you what to do.

@biodtox Golden HRE seems to be mutually exclusive with this mod

Golden HRE is a bit controversial so I released it as a separate mod

Where's Golden HRE?

Mods seems to work fine so no update needed.

Mod may be temporarily broken due to PDX changing the color of Asturias but I can't check till Saturday/Sunday.

You can take a look at the mod files to see how it looks. You'll need to find the folder where steam decided to put it in though.

@Juan The text file in \common\landed_titles has title colors. Modify the colors value with RGB value (don't touch color2). You need to copy the whole 'tree" (so if you want to change let's say France then you also need to copy Frankia to which France belongs). Delete any unmodified values (so if you don't want to change the capital delete the code declaring the capital). This helps with compatibility (the mod won't overwrite another mod with vanilla values)

How would you make a mod like this? I'm planning on making my own.

@kyzerAngelo7 Sorry for late response. Check your friends request please.

I love your colour choices. I wish vanilla ones were closer to this. The only one I'd do differently is a whiter finland.

Can you send me an file with the golden HRE for me to test? I have an personal map mod that i'm using which changes the paper map quite a lot, maybe it will look good with my mod, then i could screenshot it to you to see if you like it.

@kyzerAngelo7 I too wanted golden HRE just like in HIP, but I'm afraid it's not really possible to make it look good on paper map. I saw a mod that disables the paper map so I might try again to make golden HRE later this week. If you're willing to resign from paper map that is. I'm not so I abandoned the idea originally.

Good mod. Could you try an golden-ish color for the HRE?
