It does work to keep bugs off of the ceiling. The color is a blue with a hint of green and no there is not a standard color that is on a color chart.

Honestly, if this works, then don't you think that the paint companies should name that shade something like "Spider Repellant Blue" or something? We were talking about this at work today, and everyone is now looking for the right shade...

The classic color is Haint Blue......

and most "paint" stores I've dealt with have it in their computer by name

BUT I don't know about the spiders.....the color is supposed to discourage flies

"......measure Once.....cut Twice....

throw that one away and cut a new one...."

Hi, I am about as artistiic as a rock, but want to exrecise the left side of my brain, so looking for a work-out. Also considering for my 11-year old son who is very creative and imaginative.So, inquiring about watercolor class expectations, etc., to see if something like this might be a fit. Thank-you!P.S. Love, love, love the watercolor hanging in Dr. Yamaki's office in Federal Way. That is how I discovered your beautiful talent.
