Lead brand
Top left, larger, and its palette and font run the whole design. Pick it by audience: organisations = BHD Asia, individuals = HummingBeing, practitioners = TRE™ in Singapore.
Partner brand
Top right, smaller, in a white pill with "in partnership with". Use its horizontal lock-up and never recolour it to match.
Collaborations
Multi-organisation events (for example the Romania events with TRE România and ICF) keep every partner logo the client supplied. Don't strip one out.
