VS Code差异编辑器文本高亮颜色自定义及设置项咨询

Got it, let's figure out why your custom diff highlights disappeared and how to fix this properly.

First, the issue here is that when you set diffEditor.removedTextBackground and diffEditor.insertedTextBackground directly, you're overriding the Dark Pro Vivid theme's specific semantic highlighting styles for elements like argument_removed and argument_added. This theme likely uses semantic tokens to apply those targeted highlights, and your global color settings are clashing with that priority.

Here's what you need to do to get both the enhanced visibility you want and keep those targeted argument highlights:

1. Double-check semantic highlighting is enabled (VS Code 1.37.1 supports this, but it’s worth confirming):

   "editor.semanticHighlighting.enabled": true
   

2. Use semantic token customizations to target argument.removed and argument.added specifically for your theme. This ensures those elements retain their distinct highlights without being overridden by global settings:

   "editor.semanticTokenColorCustomizations": {
     "[Dark Pro Vivid]": {
       "rules": {
         // Tweak these hex codes to match your preferred contrast
         "argument.removed": { "foreground": "#ff4757", "background": "#420000" },
         "argument.added": { "foreground": "#2ed573", "background": "#00421a" }
       }
     }
   }
   

3. Adjust global diff editor backgrounds (optional) if you still want to tweak the overall line/character contrast. These settings complement the semantic highlights rather than replacing them:

   "workbench.colorCustomizations": {
     // Character-level backgrounds for all changed text
     "diffEditor.removedTextBackground": "#300000",
     "diffEditor.insertedTextBackground": "#002800",
     // Faint line-level overlays to make changed rows more visible
     "diffEditor.removedLineBackground": "#2b000080",
     "diffEditor.insertedLineBackground": "#002b0080"
   }
   

The key here is separating general diff styling (via workbench.colorCustomizations) from targeted semantic element highlights (via editor.semanticTokenColorCustomizations). This way, you get the broad contrast adjustments you want, plus the distinct, high-visibility highlights for those specific argument_removed and argument_added sections.

Feel free to tweak the color values until you land on the visibility that works best for you!
