Competitive analysis
I went on Mirvish, Broadway.com and Ticketmaster and created the user flow of their ticketing viewing process to analysis the user experience. And I noticed Broadway.com and Ticketmaster do not sorting the seats by colours and it takes user a lot of time to hover over the seating to explore the price of each seats. When the venue contains a large amount of seating, it consumes plenty of time on picking the best seating.
Therefore, using colour to sorting the seating should help reducing the time on exploring seating by prices. But during the usability testing of the Mirvish ticketing previewing, participants have point out they got confused by the similar colours of the prices and they have to click on each seats to review the prices.
After analyzed the user flows, I noticed they all require users to hover over/click on the seating to review the prices.
