Flat Themes

The two neutral bases (Black & Grey, White) that pair with any accent color.

“Flat Themes” isn’t a separate toggle in Aurora — it refers to the two neutral base options (Black & Grey and White) in the same Theme picker as the 10 accent colors, described in the plugin’s own materials as “10 color presets plus 2 flat neutrals.” There’s no independent flatness/depth control beyond choosing one of these two bases.
