Colour vision
Can everyone tell the colours apart?
Your palette as seen with each of the three dichromacies and with no colour vision at all. Pairs that were clearly different to typical vision but come out close are listed under each view.
Typical vision
Protanopia
no red cones
No pair collapses.
Deuteranopia
no green cones
No pair collapses.
Tritanopia
no blue cones
No pair collapses.
Achromatopsia
no colour vision
- #2D55FF and #8B6900 look the same
When a pair collapses
Do not rely on colour alone: add a label, a pattern, an icon or a clear difference in lightness. Lightness survives every kind of colour blindness, which is why the contrast grid helps here too.
The colour-vision views are an approximation of how a typical person with that kind of colour blindness sees (Machado, Oliveira and Fernandes, 2009). They are not a diagnosis or an eye test. Pairs are compared by distance in OKLab: under 0.05 they are listed as looking the same, under 0.1 as hard to tell apart. These cut-offs are RiotPad's rule of thumb, not a standard.
