I may have asked this question before, but can sand be coloured to match the surrounding natural earth?
I know that many people love the soft, flour-like white silica sand (I think that's what it's called) - and it can look nice on golf courses that are very manicured, garden-like and which make no real attempt to look 'natural'.
However, I was looking at the Black Mesa pics and I find the screaming white sand on courses like this to be just plain UGLY. Now I realize that ugly is a subjective term - and to me, when a golf course design seems to have been meant to blend into the land and appear more natural, and then they elect to use blaring white sand in the bunkers - it's like... two steps forward and three steps back.
So can sand be artificially coloured? Could the same sand with the same, cushy, pleasing, soft-and-cuddly-modern-'hazard' playing characteristics be made to appear as if it were a natural part of the landscape?
How much extra would it cost?
(And while we're at it - maybe it could be artificially FLAVOURED as well... so when it flyies into your mouth it tastes like mocha or cinnamon...)
