In which menu does Inventory_back11 appear?

[_hitsuji418]

I am currently working on a texture pack for the UI (not all menus outside the game), when I was identifying each texture, the only one I can't find is Inventory_back11 in-game.
Does anyone have any idea where it appears?

Sorry it's scratched, but the texture color is the same, just I drew the letter 'l'; I must say that the texture is not the same for the portable chests (the texture for the portable chests is Inventory_back2).

Here I show a preview of my texture pack, and as you can see on the right, more textures are seen with scratched letters (this is how I am identifying each texture, lol).

Maybe it’s one of the colors which shows up when you click “sort inventory” or maybe it’s the one used for Chest slots?

It's used for the housing menu.

I appreciate your true help, I am surprised how stupid and blind I am, seriously, thank you very much!

I already have that texture located, I know when it appears, thank you very much!
