Colour-blind-friendly palette

Closed this issue · 3 comments

Improve the contrast between points on the jitter plots to ensure that they are colour-blind friendly.

I have tested the jitter plot using Color Oracle:

Normal vision
Normal vision

Deuteranopia
Deuteranopia

Protanopia
Protanopia

Tritanopia
Tritanopia

The four different coloured dots are hard to distinguish with Deuteranopia and Protanopia because three appear to be shades of the same colour.

They look pretty good to me

Maybe I'm being too picky but I find the dark grey and dark purple on Deuteranopia hard to distinguish from a distance.
