Theming and dark mode
Roughly half your readers may be in dark mode. A diagram drawn on white either adapts or glares.
#The options
Setting | What it does | Use when |
|---|---|---|
Inherit | Follows the space default. | Almost always. |
Enabled | The diagram adapts for dark readers. | Line drawings and text-based diagrams. |
Disabled | The diagram keeps its own colours. | Brand colours, or anything where colour has meaning. |
Turn adaptation off when colour is semantic. A network diagram where red means production must not have red shifted for contrast.

#A few things that catch people out
Adaptation adjusts colours; it does not redraw the diagram. A dark-on-dark drawing stays hard to read.
Excalidraw and draw.io handle dark differently, because one is a sketch and one is a drawing.
Exported images use the light rendering, since a PDF has no theme.

Readable in both themes, without redrawing anything.
