Hello again,
Thank you for the prompt replies. Following up Gabriel's pointer, I found out this is happening specifically with Safari in MacOs. I tried using firefox and it was much better.
Anyways, I play around with CSS in web developer mode, and changing --color-font-disabled to be black would make it much better with firefox but somehow still not as good in Safari. I guess it has something to do with webkit or something MacOS Safari uses. Right now, I found it simpler to just move to firefox to open our application.
So right now my solution is using firefox with css-related extension (with just one line of code). One day I hope our company can get the professional license to play around with CSS and other nice things ๐, that would surely solve the problem.
Thank you for the pointers! And thank you for this platform, this has been a life saver.
