> yellow paper is used primarily for quick throw-away notes and scribbles in reality (at least here in the UK).
Is it? I know yellow is the default colour for sticky notes, but for everything else -- at school, university, work, home -- the paper is white.
Ryman stock over 500 notepads. Three have yellow paper, and are described as "Being Yellow in colour [they] may appeal to people with dyslexia as the coloured paper can aid reading and writing in people with this condition".
