Why does dark color scheme not work with lightTheme

[AlexMcComb]

Why does this work for dark theme:
<Provider theme={darkTheme} colorScheme="light"> &
<Provider theme={darkTheme} colorScheme="dark">

but this does not work for light theme:
<Provider theme={lightTheme} colorScheme="dark">

but this does?:
<Provider theme={lightTheme} colorScheme="light">

I'm using this for a CEP plugin, so I'm trying to match the Creative Cloud application UI "brightness" changes to match my plugin theme color. Creative Cloud applications have 4 brightnesses I'd like to match.

The light theme should apply the darkest color scheme for colorScheme="dark":

react-spectrum/packages/@react-spectrum/theme-light/src/index.ts

Lines 24 to 25 in ab0323a

	light: lightest,
	dark: darkest,

The included themes support the following color schemes:

Theme	Color Scheme
defaultTheme	light / darkest
darkTheme	dark / darkest
lightTheme	lightest / darkest

Ok, so I need the default theme for the light color scheme - thanks!
