I see a lot of negative reviews on colors but to be honest I went in there in February as a single white guy and had a great time. Maybe I was in there on a "off day". As KD87 said they were very interested in my dick. A few saying they never seen a white one before (not sure how honest that was) but I ended up playing twice in the open space area. Not a lot of privacy but if you dont mind putting on a show its not bad at all.
What annoyed me about it is the open room, particularly that it was redesigned that way. The bar used to be called Tru Colors under different management. The play room was completely private, with a security lock door. When it became Colors under new management, they took the door out and made an open space. This makes play even more difficult for non-swingers or newbies, men or women.
There is a small side play room, that's not obvious or you can't see straight into, when coming into the bar. But it is accessible by simply walking towards the back. However, if someone is in there, it's club rules that you can't enter the room and only watch from the outside.
The staff at Colors appear to not understand swinging, but rather create a kind of odd host/hostess bar atmosphere. Various staff are loud, can be annoying, and ask way too personal questions. It kills the swinging type vibe, and creates a more drink bar atmosphere, complete with pushy drinking games.
Many women there, if any are there when you come, seem to be working for the bar or are controlled by the staff. They had a fat/chubby chick walking around naked/semi-nake before, who totally worked for the bar.
Approval to have sex, with single women, seems to come from the staff first. You can sit back as a 3rd party and watch for subtle clues for this. There might be adventuristic women that come on their own, but it seems more of a shady situation. But to Color's credit, they do have some college age women come around, which is a bit more exciting than other places.
And lastly, the staff or girls have likely seen a "White" penis a number of times before. In fact, I'm sure penis of all colors. It's just a bit more rare than the usual Japanese guys that come there.
