Just finished Internet search for "silver sand" and found a number of hits, mainly in the UK for gardening. Several sites said "quartz sand" and "silica sand" and "silver sand" and are the same. I think at least one site said silica sand is finer grit than quartz sand.
Silica sand reportedly is white because it is pure quartz, colored sands have iron and other minerals coating them.
Screened builders sand to remove the coarsest particles was added to my little bit of white sand, and mottled anigre only got dark gray. Didn't think to try another wood so don't know if anigre doesn't take as much color when sand shaded, or the combined sand isn't as effective.
