Designing Accessible Color Systems by Stripe

Color contrast is an important aspect of accessibility. Good contrast makes it easier for people with visual impairments to use products, and helps in imperfect conditions like low-light environments or older screens. This article goes in depth on how the Stripe team came up with a color palette that fits their brand, is beautiful, and still accessible. Unfortunately no tool (yet?) to play around with. I hope they will release more of this to the public soon.
