The Ordnance Survey Blog has announced a colour scheme that accomodates people with colour vision deficiency (CVD) — i.e., colour-blindness. “Rather than creating separate colour schemes for those with various forms of CVD and those without, we were working on a colour palette that would work for everyone. Well a year later and we think we’ve cracked it and are now close to releasing a colour scheme for use with OS VectorMap Local, our customisable digital mapping product.” Above left, their regular scheme; above right, the new CVD-friendly scheme.
