sjcro Posted February 26, 2021 Report Share Posted February 26, 2021 The double dummy markers in green and red are not distinguishable for many people who are color-blind because red and green look the same. Would it be possible to make the red ones a different shape from the green ones? Or to distinguish them in some other way?. Eg. with - and +? 1 Quote Link to comment Share on other sites More sharing options...

I have pointed this out in detail with references elsewhere.5% of all men are red/green colour-blind. The data did not say if that included Bridge-players but I have no reason to believe it would be different. 1 Quote Link to comment Share on other sites More sharing options...
fredwardwe Posted February 28, 2021 Report Share Posted February 28, 2021 Very much agree. Use squares or much bolder colors or something. Quote Link to comment Share on other sites More sharing options...

The solution is to use magenta instead of red - this solves the problem.Which side is easier to read? 1 Quote Link to comment Share on other sites More sharing options...
