The logo design was copyrighted in 1995. A derivative version was copyrighted in 2009 and is used on the business cards. When used by the National Docent Symposium Council, the logo is black. Symposia are urged to incorporate the kaleidoscope into their own logo. It may be in any color but must be used in its entirety, complete with the copyright circle.
Docent webmasters may download the official logo here. Do not alter the logo other than resizing it to fit your docent website.
