I respectfully beg to differ. Grey/green--or cratex green, as I came
to call it, was the color that I chose for my current studio floor
and I've found it to work really well. The actual color was "Kossack"
from the Fuller Obrien paint co. here in Seattle. It was an oil base
I chose this color because I found that it blended the following
-Stones, gold and silver "pop" on it.
-It seems to hide much of the dust that I produce.. Either from hand
sanding, grinding or, most of all, flex shaft abrasives-- like
cratex. (My bench exhaust doesn't allow much dust down to the floor
anymore, so this isn't any longer so much of a point ...)
-Chair wheel and rubber heel marks don't show.
-Burns, while visible, don't pop like they might on a white or beige
I don't think that dust and grime would be hidden for very long on a
black floor. Look at any black car and you can see that the dirt is
showcased. Flat finishes, I think, will show scratches, skuff marks
and drag lines (from tanks, wheels, dragged stools, etc.) much more
than will a satin or semigloss. This may seem counterintuitive, but
when you think about it, many scuffs and scrapes actually burnish the
surface while marring and might show more against the flat. They are
also more difficult to clean. Especially spills.
Good luck in choosing a color and don't forget to pick one that , in
the end, you enjoy walking across and spending time on.
