New Sona problems with color blindness

Hello everyone. I don't often post in the forums but I feel that someone needs to at least bring some attention to an issue a few of my friends seem to be having. I am not sure if this is the correct board for this, but I figure it falls into this category since it isn't a "bug" per say.

Two of my friends can not see the color red, and describe it to me as seeing it as a brownish color instead. This also means that they can not tell the difference between the colors blue and purple. "Protanopia" I believe it is called.

Basically the problem is that they can not tell the difference between Sona's Q and her E except by noticing the glowing hands or the speed blur. With Riot's emphasis on readability I thought that I would take it upon myself to point out this flaw. I do not know how many others are effected by this problem, but this obviously something that I feel should be at least looked into. I do not know if it would be a lot of work to change it so colorblind mode would have different colors, but surely something can be done for those like my friends.

Thank you for your time.
