CAS Accessory Help!!!!!

Hello everybody, so let me start off that I'm not a pro at Blender. That being said I'm not a amateur, I've used blender to make poses and convert in game objects into accessories but I'm at wits end trying to make this perfect. So recently, when I bought Country Living, I decided I wanted to have my sim have a country wedding but I wanted to find some CC that would be perfect for a Country Wedding. I found a hairstyle and veil that looked absolutely adorable together. The hairstyle is by Mlys_simblr and the veil is by Candycottonchu (Please note that I made sure that I was allowed to edit/recolor these CCs, I looked over on both of their Tumblrs and have seen that recoloring and remeshing is allowed. Candycottonchu doesn't want her meshes to be added with new meshes, however I have no idea how to not include meshes but to be honest I wasn't planning on posting the new mesh on any site. This was for me and my personal use ONLY. Mlys_simblr seems to not mind if her meshes are added and I know that I can recolor/remesh her hairstyle because someone else already did it and it was the exact same hairstyle.) Anyway, I really liked Mlys_simblr's Sibel Rolled Updo and Candycottonchu's Daisy veil just works so well with it, but the problem I'm facing is the hairstyle's headband. I want my sim to have brown hair but the headband color is like a burgundy and that really doesn't go well with the color theme I'm planning (I'm planning a blue theme). So I thought I could use a different color headband by editing out the hair and have the headband as a standalone cas accessory, for a while I couldn't get to show up in Sims 4 studio but when I figured out what I did wrong I was able to get it to show up. But when I placed the headband in the game and used Candycottonchu's veil, a long blue streak showed up on the veil. I tried adding the veil and headband together but when I added them together the veil had black edges on the bottom. Now I'm stumped, what do I need to do so that there's no color on the veil whatsoever, or what do I do so that the veil doesn't have black edges? Any help will be greatly appreciated.


Thanks


P.S. Sorry for the long post, I like to explain things in detail
