Is there any way to gather or produce a blank, solid, white block in Minecraft? Iron blocks come kind of close, but you can see markings on them. White stained clay comes close, but it's got a little bit of red mixed in. Etc. Is there anything that's just pure, blank white? This has to be in vanilla though.
It sounds like a resource pack is fairly vanilla. The reason I was asking this though was that I was wanting to make an East-Asian castle/pagoda-looking building on a server that's fairly restrictive against mods, and it looks like a resource pack would not affect what other players see.
