In case you haven't already figured that out :) The title of the email is in reference to the two colors I'm posting this week--L-Dopa, which is the precurser to Dopamine, one of the main neurotransmitters responsible for reward-motivated behavior, and Cassiopeia, which is located in the Pac-man nebula (and is Pac-man ghost colored!)
Yeah...my toddler has been sleeping with us so I'm kinda short on sleep :)
