I saw a horse on this beach.
It was the same color as all the colors you see in the picture accompanying this text.
The horse was the whole beach itself running around and around on a lead.
In the late afternoon sun the animal was shifting between rusted metal, pale smoke, misty blue sky, wet and dry sand, sloppy dark mud, visible and invisible.
If I had been able to take a picture of it, you would not have seen it anyway.
