Is there a way to have the font in vega auto adjust when the theme is changed in Kibana (light/dark modes)? I've tried the code below but it's not working. Basically, looking for white font when in dark mode and black font when in light mode.
```auto
{
"$schema": "https://vega.github.io/schema/vega/v5.json",
"signals": [
{
"name": "isLightMode",
"value": false,
"update": "'#FFFFFF' === '#FFFFFF'"
},
{
"name": "textColor",
"update": "isLightMode ? 'black' : 'white'"
}
],
"marks": [
{
"type": "text",
"encode": {
"enter": {
"fill": {"signal": "textColor"},
"fontWeight": {"value": "Bold"},
"fontSize": {"value": 15},
"text": {"value": "Event List"},
"x": {"value": 10},
"y": {"value": 20}
}
}
}
]
}
```

Hi @Ryan_Clark,
Welcome back! Sadly there is not currently a way to detect the Kibana theme used in Vega. But there is an [open issue in GitHub](https://github.com/elastic/kibana/issues/178254) for this feature if you want to watch it for updates.
Hope that helps!

Thanks for the confirmation. I ended up finding a font color that looks "OK" in both themes. I think it would be a good feature to have, I'm glad there is an open issue for it already.
