The point that I was trying to make was that there is no possible way it could be a color calibration issue (at least to my mind), because the screenshots look different even on the same screen as you see above in my original post.
If it was simply a calibration issue, then both of the screenshots should look equally wrong. However, in this case, you can clearly see that the 2 images have different color information contained within them.
I'm still guessing it's a calibration issue.
Open a command window on both computers. (cmd.exe from the search bar)
Click the icon on the top left of the console.
Go to "Properties"
There's a setting there where you configure your console default colors.
Check the shade values; I imagine one of them is different than the other.
QB64 just tells the console "use color 1, use color 2, use color 3"... Windows, and the user, has the option to configure those colors to whatever the heck they want.
