Making a 1:1 scale replica of this castle but am unsure of which blocks to use for the exterior. /u/Appropriate_Twist_86 Minecraft on reddit

This is Castle Del Monte and im making a exact exterior replica (1:1 scale) on my Minecraft server. Ive tried some different blocks but sandstone looked too yellow and calcite wasn’t bricky enough. Any help is amazing thanks 🙏
