Hi all,

I am in favour of changing the defaults to a sequence whose two (or 
three if reasonably possible) first colors are distinguishable by color 
blind people. I know that those settings can be changed by the user, but 
it is an additional pain as for every tweak of that kind.

It turns out that my PhD advisor is color-blind, as is the student that 
works next to me. As I am too lazy to change the defaults by myself, I 
keep having to tell them which curve is what data everytime I discuss 
with them. This is an accessibility problem.

Best regards,

Timothee

P.S.: The oscilloscope I am currently using in the lab as the same 
problem : channel 1 is yellow, 2 is green so these two are 
indistinguishable, and 3 and 4 are purple and gray, not the best choices 
either... and impossible to change
