a screenshot created dimension in minecraft 20w14infinite. looks very good! I guess different dimension have different color change (like if you enter one of these dimension your skin can look different than it looks normally). If I am correct this dimension have elder guardians dolphins a lot of iron ores, illusioners, pillagers, something like caves iwth shape of cut in half 3D circle fillled with flower pots with red mushrooms. there is even dragon and withers fighting with vexes.
