No decision was required regarding jersey colours as Munster and their opponents, ASM Clermont Auvergne, will wear their traditional red and white respectively.
Saracens, meanwhile, have secured home changing room advantage for their semi-final against Toulon at Twickenham Stadium on Sunday, 28 April. The toss for jersey colours also went the way of Saracens who will wear black and red for the second Heineken Cup semi-final in the club's history.
The coin tosses were carried out by ERC Match Officials Performance Manager, Donal Courtney, in ERC's offices in Dublin, and all four clubs had the opportunity to watch proceedings by video conference.
Tickets for the Saracens v Toulon game are currently on sale on Ticketmaster at www.ticketmaster.co.uk while tickets for Clermont v Munster are available through the normal club channels.
