In the long-term use of vscode, I found that the number of method parameter overloads has a dark foreground color, and my eyes will be tired if I see it for a long time. I ask the teacher to allow us to modify the foreground color to our own suitable foreground color. It will be great for people who have been coding for a long time! Hope this problem can get your support and help from the teacher to improve it in the next milestone. Thank you very much! !
I would advise you to switch to light theme, is what I recommand. !
Thanks for your answer! But looking at the light theme for a long time will make the eyes more tired. These are one of the UI elements that are used very, very frequently. Improving it will be very friendly to most people. From the picture you provided, it can be seen that even in the light theme, it is also very dark, and it takes a very difficult time to recognize it.
If you want to improve the situation more perfect, it is recommended to add the following oval background color settings, which will be very beautiful and modern, and can bring people a very pleasant coding experience more in line with ergonomics. !
The contrast on the numbers needs to be increased. Here's the relevant css:
I would recommend these themes below : official dark pro is coming (dark black) Choose the one which is comfortable for you after trying with all the three hope i was helpful

Hello, teacher! Is it convenient to modify the style of this css?
Hello, teacher! This problem is really important to me, because my eyesight is not very good, so I hope you can accept it and help solve it in the next milestone. After solving this problem, I will no longer report UI-related problems in the future. I really hope you can help solve it, thank you very much for your hard work and efforts!

Hello, teacher! VSCode is a great project that gives users the greatest autonomy from the very beginning, allowing users to personalize configurations according to their own habits, so it can fully surpass the long-born jetbrion series in just 5 years. The most important reason is that VSCode's open source thinking and allowing users to customize and configure VSCode development methods to the greatest extent can achieve today's achievements. I hope VSCode can continue to develop this way of thinking and development, focusing on every reasonable request of users and need. Thank you here! vscode contributors

Hey! I also think that text should be more readable. I created a PR to fix that:
