Does anybody know why the reasons why some beaches have pink, white, and black sand and where you can see this.

Sand is pretty cool in a geological-paleontological sort of way... Sediments come down rivers - the heavier stuff, mostly silica rock crumbs, drop out 1st as it reaches the ocean ( the lighter stuff - clays, minor sediments, & dissolved minerals, are carried further out to sea). So you get beaches. Impurities carried down from the rivers give some of the colors. Volcanic areas have black beaches because lava (black) is shredded by the wave action & makes 'sand'. Pink beaches have alot of ground up coral in them...mostly island areas with lots of wave action ie. Hawaii. If its white it's mostly quartz, pure silica sand.
Just love beaches & oceans, but esp islands....

Sand has elements and minerals in it other than silica (that is, quartz particles) which are the greater part of most sands.
These elements and minerals come from the rocks the sand is made of; iron-rich rocks give a reddish colour, sands from basalt and other volcanic sources may be black or even green. Very white beach sand is usually derived from quartz and limestone rocks, and is often full of bits of shell and other debris from sea-life.

The beach is at Alum Bay on the Isle of Wight. I don't know if you have to pay to visit the beach, but knowing how commercialised we are as a nation it's probably the case. I'm sure you can still buy souvenirs (or even packs of sand to craft your own displays) but they're probably quite expensive too.

Because sand is just broken down rocks so ya know

Mostly a link between the minerals and bacteria in the sand
