If we want to consider some geomantic omen in the outdoor garden, I think we can basically build a rockery and get some running water, so that there are mountains and water, and the homonym means that there is talent and potential, and we can also get some fish, which can form a side view combining static and dynamic. As for the color of floor tiles, I think generally speaking, considering it is outdoor, you can try to use some dark colors, such as brown, which will look better overall.
