I made the end a bit more purple, look at the pics, you should not need Optifine. However, I know you'll need it for the certain textures to glow. To get rid of the Nether portal textures go into the recourse pack folder assets>minecraft>textures>blocks and then Ctrl+LeftClick on the Nether Portal and Respawn Anchor, then Right click and then select delete
PS: This is my first Texture Pack! :) Hope you like it!
Also: there are 2 more textures changed, they are from the same place, they are in the Warped forest, find them!

(This pack is done being updated, also, what the heck is with the endstone on warped??)
