thanks for taking the time to help me out :)
I am having trouble deciding which color to pick. A bright yellow or a bright purple. It has to go with the teal I used because it represents my school, which will be my primary color. I have googled/asked people and found conflicting answers.
 I have revised the purple color to the purple based on feedback from Reddit from people who are colorblind. My goal isn't necessarily to have everyone be able to identify the yellow or purple. My goal is to provide the best contrast between the teal and yellow or purple. [/edit]
I have read anarticle and it gives a list of combinations to avoid.
Green & Red
Green & Brown
Blue & Purple
Green & Blue
Light Green & Yellow
Blue & Grey
Green & Grey
Green & Black
I highlighted two of those combinations because teal is kind of green and kind of blue, which disregards both yellow and purple.
Here are the links to the color combinations using Google's Material color helper.
Of course any suggestions with different colors are welcome too!
