The Chromatic Yuletide Challenge is an offshoot of both Yuletide Exchange and Dark Agenda. Dark Agenda encourages the production of fanwork that centers around "chromatic cultures and characters," where chromatic is used as an umbrella word for "'person of color', 'non-white', 'multiracial', 'indigenous', 'sourcelander', 'hyphenate', 'diasporian', etc." A story that features chromatic cultures and characters can be posted to the Chromatic Yuletide Archive (in addition to being posted at the main Yuletide Archive).
