I’ve created a Google sheet which allows the creation of colour lists more suitable for colour-blind participants than the standard primary colours one might use.
The reference for the colours is Tol (2021).

Please use this thread for discussions about colour sets suitable for experiments in PsychoPy. Feel free to ask me to add schemes to the Google doc.
For more details about how I recommend using colours in code components, please see my crib sheet.
