In the teacher dashboard for the "assignments" tab, it is incredibly difficult to see how students did on their homework at a glance. I am red-green colorblind and when I look at something like this:

I can only see a difference with the yellow color. Just by glancing I cannot tell the difference in color between 0's and 100's.

Obviously I can look at the numbers and tell how my students did, but color makes it much easier to see. I have been experimenting with color (and self-reporting) to get the following chart that I would argue is much easier to see:

A better way for color coding to work is to move around more of the color wheel while trying to avoid commonly confused colors.

Having a better color coding on Khan Academy would be great for teachers (and especially color blind teachers like myself) to quickly see how students are doing.

If anyone is interested in the conditional formatting options I have on Google Sheets, here they are:

lower: light red berry 1

midpoint: yellow

max: cornflower blue
