Throughout the show, the host provides the men and women with additional insights by providing personality profiles showing which contestants are their best matches and also allowing them to view items the others have brought to the house, such as items of clothing or luggage.
Other episodes include sketch artists drawing contestants' impressions of each other.
A separate infrared camera films the person on the dark side's reaction; the two images are combined in post-production.
This is done, in part, by using video editing software to fade the infrared image of the person being revealed to black before they are illuminated, then seamlessly showing the color image of the person being revealed as it is faded in and out.
During the reveal process the couple must remain silent.
While being shown in the light, a contestant cannot see the other contestant's reaction.
Initially, all six contestants have a group date in which they all sit at a table in the dark room exchanging names and getting to know one another's voices and personality types.After this date, each contestant can invite another contestant for a one-on-one date; these dates are also held in the dark room.
