This conference is targeted to the independent school (nonprofits) development leaders — essentially those people that raise money for their schools by working with parents, current students, alumni, board members, and the community.
Maybe I could use yellow as a second accent color (when red is the only one, it creates too more tension, when used with the dark background)? As there will be quite a big audience, I'd suggest sticking to the dark background (dark chalkboard), which decreases the visual noise and looks more powerful, than the light one (in your case).
