deleting my original reply here since I went and played with things and this is what is happening...
I am logged in and seeing the old color scheme,
I click on "log out"
I get a screen "all cookies are cleared" that page is in old color scheme.
I click on the option of previous viewing page, the forum index, mothering, anywhere that might take me back to mothering discussion it takes me to the new updated way mothering looks with the magazine info up top. (remember I am no longer logged in)
While I am still logged out I can click anywhere and everywhere, random forums and threads and I'm still seeing the new version with the magazine info up top, can hop skip and jump through the forums and still see the new way.
As soom as I log in I am taken back to the old color scheme and the magazine ifo is gone.
