I am debugging some code in the IDE. I hit a breakpoint, I just need the highlight on the current line I am stepping to be a little more “in my face” darker, different color, brighter, something. My tired old eyes dont register the soft, soft gray the current line is 
Is there a way to change that?
thanks!
Hi @roujesky. Arduino IDE comes with multiple UI themes. You can chose the theme that provides the coloration which meets your preferences.
If you haven't already try the other themes to see if one of them meets your needs:
- Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
The "Preferences" dialog will open.
- Open the "Theme" menu in the "Preferences" dialog.
- Select a theme from the menu.
- The Arduino IDE UI will immediately switch to the new theme, providing you with a preview of how it looks. If the selected theme is not to your liking, try selecting a different one.
- Once you have selected the theme you like, click the "OK" button in the "Preferences" dialog.
The dialog will close.
This is how the line highlight looks when using the "Light High Contrast" theme:
And here is how it looks with the "Dark High Contrast" theme:
I think both of those could be described as "in your face".
If none of the preinstalled themes meet your needs, it is possible to install 3rd party themes, or even make your own theme. If that is needed, just let us know and we'll provide instructions. However, I do recommend the preinstalled themes as these are the only ones Arduino verifies as working correctly with Arduino IDE.
You are welcome. I'm glad if I was able to be of assistance.
