I understand it was developed by the British Airports Authority to be a typeface and colour scheme to aid reading at a distance and while moving. Black on yellow for passenger information, and yellow on black for staff instructions.Black on white is drab. Isn't the universal airport yellow on black/grey supposed to be highly readable?
However, it isn’t universal, and is actually a copyright of Heathrow Airport and its parent company (which also owns AGS Airports) as the successor to BAA. That’s why airports like Gatwick and Edinburgh had to change all their signage when they were sold off. That was stated by a member of staff on a Gatwick do a few years ago where they said they had a deadline to change the signage as their “previous owners” had only given them a 1 year license to change the design.
I definitely prefer that style of signage, and as the majority of flights I take start at Glasgow and either end or connect through Heathrow, it’s the style I’m most used to.
