hey, does anyone know why the sand often appears yellow/beige when viewed through our eyes...? :)

[sandgrainsDotCom]

The beige color of sand is a combination of all the colors that exist in the individual grains. Most of the individual grains are too small to see, so the resulting color is usually beige.

I will not bother, as I lack the knowledge, to comment on *why* grains of sand reflect the colors they do but I can comment on why grains of sand appear in such a color that you perceive in case you're uninformed.

The fact is that colors reflected to your retina are simply wavelengths of light not absorbed by the object and thus are sent back out into the atmosphere/area they are in.

In other words: Photons are weird and carry all sorts of properties.
