		| Abstract: | 
		The observation that AGN host galaxies preferentially inhabit the “green valley” between the blue cloud and the red sequence has significant
 consequences for our understanding of the co-evolution of galaxies and black holes via accretion events. I discuss the interpretation of green valley AGN 
 host galaxy colours with particular focus on early-type galaxies. |
