What you did

I set the background color in a project using Color::Lcha {...}.

Minimal example:

fn main() {
    App::new()
        .insert_resource(
            ClearColor(Color::Lcha {
                lightness: 80.,
                chroma: 20.,
                hue: 100.,
                alpha: 0.,
            }), /*.as_rgba() makes the problem go away */
        )
        .add_plugins(DefaultPlugins)
        .add_startup_system(setup)
        .run();
}

fn setup(mut commands: Commands) {
    commands.spawn(Camera2dBundle::default());
}

What went wrong

With great anticipation, I awaited the sight of a mesmerizing background color, one that would transport me to a world of beauty and wonder. Alas, my hopes were shattered as the app crashed before my very eyes, leaving me stranded in a void of disappointment and frustration.

Converting the Lcha color to RGBA yielded the expected result, but I found the crash quit surprising, since all other variants of Color can be used to set the background color.

[payload]

There is a wrong return value in Color::as_rgba_linear. I make a PR
