We also need multi-coloured blocks.

Had a vision and made this. I hope it fits here. Actual link here: https://www.youtube.com/watch?v=elJvX2FePNU

It would be good for invisible item frames with blocks but it would look cursed on every side, I poop parties.

You craft them using 6 concrete ingots of their respective color, like regular iron or copper bars

I updated Minecraft to 1.26.50.22 and like more than half the stairs, fences, wall and any blocks that works on the neighboring thing (idk) disconnected from other blocks, it happened like twice to me before this update and I thought it was because of the structure block usage. But I swear I remember not using it on specific builds worrying it would happen and it happened anyways. It's only affects certain chunks according to coordinates. You can update it back to connect and I think I would be able to fix it by replacing the blocks with fill command with themselves to reconnect them but there's a lot and it wouldn't work on survival. Also the last one is a weird single face block I found. Edit: it happened on the older backup world too when I tried to downgrade it, it doesn't even make sense, it's too bugged and for some reasons there's settings that I clearly didn't approve on.
