--splashBackgroundColor not working on android

I am running capacitor-assets version 1.0.14 to generate icons and splash images for an android app. I scaled down the size of the icon to about 68% and that mostly gets the size right, but the splash background color is just coming out white. For reference, this is the command I'm using:

`npm run capacitor-assets generate -- --android --iconBackgroundColor "#80daeb" --splashBackgroundColor "#80daeb"`

That correctly generates all the "drawable..." splash images with the correct light blue color, but when I launch the app the splash screen has a white background. Thanks.
