Here is a screenshot from Windows 10, the app icon it's almost invisible.

A good hack around this would be to change the Windows color bar through the settings > appearance. Some lighter colors or black would be good. Logo's are made of colors, this problem would arise in any logo that would be made.
Perhaps have it have a dark background like it does as a start tile
I know i can change my task bar color, but we are in 2018 almost 2019 and this icon is really poorly designed with just one color, someone rush it out.
this is being tracked in https://github.com/Microsoft/vscode/issues/71827
