ReflectRemote on a foreign type nested in an Option

[nulldatamap]

Hi, I'm in the situation where I have a component that looks like this:

#[derive(Component, Reflect, Copy, Clone, PartialEq, Debug)]
#[require(Position)]
pub struct Sprite {
    pub id: u8,
    pub layer: SpriteLayer,
    #[reflect(remote = ColorRemote)]
    pub fg: Color,
    // Option<ColorRemote> doesn't impl ReflectRemote 
    // OptionRemote<Color> can't be generated because of the missing Reflect on Color
    // OptionRemote<ColorRemote> proxies to Option<ColorRemote> not Option<Color>
    #[reflect(remote = ???)] 
    pub bg: Option<Color>,
}

The Color type is a foreign type, but I've used #[reflect_remote(Color)] to create a ReflectRemote type for it, but it doesn't work when the Color is in an Option. What's the expected way to handle this situation?
