Is there a way to access mechanics from the new official game mode "Color Clash" in the Creative menu yet?

See above title of topic.

No, they haven’t been released yet.

Impossible, I tried and it just not here yet

Thanks! Sorry for the inconvenience.

No, this isn’t added yet, but I’ve been working on a “rip-off” way to make the color tiles. I do expect this coming in a future update, though
