shippedTaupe is paired with #2fca21 in 8 real palettes, including Obsidian's brand system and WhatsApp's brand system, as the text colour against it.
Violet #ee82ee
complementaryViolet sits directly opposite #2fca21 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Hot Pink #ff69b4
