In a small village in an alternate dimension where gravity occasionally reverses direction for certain objects based on their color, Indigo, who wears a green hat, and Sahil, who has blue shoes, are standing in a field playing catch with a yellow ball. Above this field, there is a patchwork quilt of magenta and orange, held aloft by the quirky gravity that affects only orange objects. Nearby is a table with a collection of colored water bottles: red, blue, and green. The weather in this dimension is unpredictable, and a wind that can change the color of any object it touches is expected to blow through any minute now, potentially altering gravity's effect on them. Indigo and Sahil know the following rules:

1. Gravity reverses for blue objects, causing them to float upward.
2. Green objects are immune to gravity changes and are not affected.
3. Red objects become exceedingly heavy, irrespective of their actual mass.
4. Yellow, magenta, and orange objects switch between normal and reversed gravity with each wind gust.

Given these properties and the knowledge that the wind is about to change, what can Indigo and Sahil expect to happen to the items in their environment when the wind sweeps through the field?
First, we should consider what may change with the wind and what will stay the same. Indigo's green hat and the green water bottle on the table will remain unaffected by both the wind and the whimsical gravity, as green objects are immune to gravity changes.

Sahil's blue shoes, however, complicate his situation. When the wind touches them, if their color changes, they may no longer defy gravity, and Sahil could stay grounded. If the wind doesn't affect their color, or turns them a shade of blue still, Sahil's shoes will cause him to continue to float. Therefore, Sahil should be alert to the possibility of being carried upon the wind or staying put based on the post-wind color of his shoes.

Next is the fate of the yellow ball that Indigo and Sahil are playing with. Since its color determines that it oscillates between normal and reversed gravity, the initial gust of wind will likely cause it to shift its gravitational behavior. This means that if the ball has normal gravity before the wind (as it is being played with, it presumably does), it will start to float upward after the wind changes its gravitational effect. If the wind changes its color to anything but yellow, magenta, or orange, its behavior will then correspond to the new color's properties.

Let's take a closer look at the magenta and orange quilt overhead. Since only orange panels are affected by the quirky gravity, during the wind change, the magenta patches will stay put, but the orange patches will undergo a change. If they presently defy gravity, they will return to normal, and if they're being subjected to ordinary gravity, they will start to float. This may result in a somewhat chaotic flapping of the quilt, as some panels ascend and others remain stationary.

Lastly, we consider the water bottles. The green one will remain unaffected, as mentioned earlier. The blue bottle will begin to float away if it is not secured, considering it doesn't undergo a color change due to the wind. The red bottle will turn extraordinarily heavy when touched by the wind, assuming its color remains, or the wind turns it red. Consequently, the table itself may become unbalanced or even collapse under the increased weight of the red bottle if the bottle were a different color before the wind and changes to red.

The factors that Indigo and Sahil can anticipate upon the arriving gust of wind are as follows:

- Indigo's green hat will steadfastly remain on his head, unaffected by wind or gravity changes.
- Sahil may experience continued buoyancy or may not, depending on the final color of his shoes after the wind.
- The yellow ball will most certainly begin to float upwards unless the wind changes its color.
- The magenta and orange patchwork quilt will display a discordant pattern of movement, with the orange patches possibly switching between floating and staying put.
- The table will either remain stable, become lighter if the blue bottle floats away, or potentially collapse if the red bottle becomes supremely heavy.

Each item's fate ultimately hinges on the wind's effect on their colors and the rules corresponding to those colors. Indigo and Sahil would need to brace for a mix of levitating and grounded items depending on the wind's passing.
