[BUG] Accessibility Bug: Syntax Highlighting Contrast Issues in PowerShell (SQL/C#)

What's Wrong?

I am using Claude Code via PowerShell on Windows 10 for C# and SQL. The interface uses so many colors (yellow, red, green, blue, white, etc.) that it is impossible to find a background with sufficient contrast for all of them. Regardless of the color scheme or background I choose, some text remains unreadable. I have spent a lot of time trying to fix this but haven't found a solution. Claude suggested using only white text, which is the only thing that works so far. I think this is a design bug that makes the color schemes useless. Initial issue was blue SQL on blue background

What Should Happen?

Use fewer colors in syntax highlighting
