The new color brightness of wool and stuff in 1.12 is a bit bright and burns my eyes so I was wondering if there's a pack made that makes them the colors they are now in 1.11?
If there isn't could one be made? I know many other people out there that hate the new brighter colors of the wool and everything.
You'll have to make your own. Redistributing Mojang's assets is against the forum rules (See the Mapping and Modding section Rules for details), so nobody can give you one. I'm also going to lock this thread after posting to prevent anyone from 'helping' by way of a copyright-breaking link or download.
If you want this, I suggest checking the All Inclusive Guide to Texturing (Pinned at the top of this forum) and learning the basics of how to assemble the pack. Making this should only take an hour or two since it's just basic file managing with no assets actually being created. If you have questions, please post them in the Resource Pack Help forum.
