I hope it is okay to post this here, but I have no experience with editing resource packs and want to change the portal color from various shades of purple to various shades of green (like the portal from World of Warcraft). I want the main color to be a bright lime green with dark green accents. I tried doing it myself with the Nova Skin resource pack generator but had no success. I attached a picture of how I want the portal to look. I've also looked on different sites to see if someone already made the changes but had no success with that either. Thank you in advance.
