How to increase the contrast between background and font

With the new gray background and gray font, it is difficult for some projection boards (and some old eyes) to see. Here’s my question:
Is there a way to provide feedback to Desmos that an option could be offered to view in the previous black/white contrast? A while ago you could email the team and ask a question.
Any help would be greatly appreciated. I know with CL the font can be bolded and changed to black but I was hoping for a different option so when viewing activities it is easier to see.

Hello there!

You can email with any feedback or questions. Thank you!
