I am participating both in requests and offers. All 4 of my fandom requests feature characters of color (though in one I do have an option of a non-chromatic character and in another the CoC doesn't have a name so I've specified him in the notes and can't guarantee anything). I've made it clear in my Dear Writer post that I'm participating here.

I'm offering a heavy chunk of chromatically focused characters in my offers. And regardless of what I get assigned, I plan to write some of the chromatic requests I see during Madness.
