Unexpected color changes in diagram (dark mode)

[oliversalzburg]

Yesterday I started work on a diagram on diagrams.net and wanted to continue work in VS Code today. When I opened the diagram, I was confused that some elements seemed to have changed color. Previously black rectangles were suddenly white, which was very confusing.

After reading #4, I assumed this could be connected to dark theme adjustments. When I manually set "hediet.vscode-drawio.theme": "atlas", my diagram elements would also turn back to my expected dark color.

I fully expect this behavior to be a result of user error and not having defined my color correctly initially. But maybe it's unintended behavior.

I hope this piece illustrates what I was experiencing.

I think the same thing happens when you change the theme on the draw.io website. I could change the default theme of draw.io in VS Code to atlas. Currently it is automatically derived from VS Code's theme.

I see. Well, in that case it's probably not worth tracking here. Maybe I can find the right place upstream 😄 Feel free to close this.
