I just taped a show for CNN with Christine Romans, the chief business correspondent.

I wore red for Ed, as so many teachers recommend.

At Mayor de Blasio’s inauguration, I will wear green at the request of Lace to the Top, an advocacy group of teachers. On the Jon Stewart show, I wore a green plastic bracelet sent to me by Lace to the Top.

Now I learn that on December 9, there will be a national day of action to reclaim the promise of public education. Instructions: wear blue for solidarity.

So there you have it: red, green, and blue.

Anyone want to add some more colors so we can truly be a Rainbow Coalition?
