I believe this image is one of yours - if I am wrong, please ignore this message.
IMO, it would make the image better if the top right anti-color triplet was rotated so that the relative anti-color positions match that of the Venn diagram on the left. Are you able/willing to do this please?
Also what is the "G" in the diagram?

When used in a WKB approximation, it can be generalized to, . But since this approximation is only exact in the limit that there is no dependence on position or time, I agree with the way you stated it in the formulary: Once students understand the basics, they can learn the generalizations (vectors, spatial/temporal inhomogeniety) later.
But this seems to be a typo:
It should be replaced by something like this, to represent the fact that omega is a function of k:

Hello. I saw your animation on torque. I have no ability to create animations, but yours is very close an animation that I imagine that would intuitively show how precession arises. We already have animations that demonstrate what precession does, but I have not seen an animation that shows how precession comes about. If you would like to collaborate, let me know.

On 8 January, 2014, in the talk page for the Color charge page, you mentioned that Roger Penrose (in his book The Road to Reality) uses the red, yellow, blue naming scheme for the colors of quarks rather than the typical red, green, blue. You also edited the page to include this information, but it has since been edited again, and so it no longer does.
In Tony Zee's Group Theory in a Nutshell for Physicists, the author adopts the red, green, yellow naming scheme, differing from both the standard convention and from Penrose. I've been looking into the origins of these discrepancies, but tragically, neither Penrose not Zee seem to cite any sources on the origin of their naming schemes. As you made reference to it in an edit of the relevant page here on Wikipedia, do you perhaps have some insight into these naming issues and their origins?

On 23 August 2012 you added a redirect from Color symmetry to Color charge with the comment "redirect for now, can expand at any time".
Recently I have created the articles Dichromatic symmetry and Polychromatic symmetry. I now propose to remove the redirect, and replace it with a disambiguation page for Color symmetry with entries for Color charge, Dichromatic symmetry and Polychromatic symmetry. What do you think?
