Color-Blind-Safe UI Palette
Used by developers, writers, and creators worldwide.
A color-blind-safe UI palette generator returns a set of categorical colors chosen to stay distinguishable for viewers with the common forms of color blindness. It draws from a well-known, research-backed qualitative palette whose colors separate clearly under red-green and blue-yellow deficiencies, then returns as many as you ask for, with slight variation on each run. This matters most for charts, maps, tags, and status systems where colors carry meaning and must be told apart by everyone, including the roughly one in twelve men with a color-vision deficiency. Designers and data-visualisation developers use it to pick series colors, category labels, or legend swatches that remain readable for the widest audience. Each value is a paste-ready hex code. Combine the palette with non-color cues like labels, patterns, or shapes so meaning never depends on color alone, and your visualisations stay clear for all users.

FAQ
how is this palette color-blind safe
It is built from a qualitative palette designed so its colors remain separable under the common red-green and blue-yellow deficiencies. The hues and lightness levels are spaced so categories do not collapse together for most viewers.
do i still need labels and patterns
Yes. Even a safe palette should be paired with non-color cues like direct labels, patterns, or shapes, because no palette is perfect for every form of color vision and color alone should never carry meaning.
why limit the number of colors
Distinguishable categorical colors are a finite resource; beyond about eight, even color-blind-safe sets start to look alike. Keeping the count low keeps every category clearly separable.
