hot or cold design

A couple of designers from portugal came with this design for bedding sheets:
"Couple(name of design) can be a game or a monitoring system.
The ruler is printed so as to be readable from inside the bed.
The numbering rises outwards and from warm to cold colours.
Each person knows how much he or she can pull and how far apart the couple rests."
