Help with some statues

[Victorlomu]

I'm new playing stardew valley and I found some statues with different color rocks, I don't know their purpose and I found anything, I will be so grateful if you know

These are warp statues. You don’t really interact with them. You’ll figure it out after you find your first warp totem.

These are the warp targets for items you will get later in game, allowing you to teleport from one place to these statues.

There are quite a few places in the game that are far enough away that warp is necessary if you go there on a regular basis. Depending on where you are in the game, you'll use them more frequently.
