shippedTaupe is paired with #99ec69 in 6 real palettes, including 7-Eleven's brand system and Astro's brand system, as the lead colour.
Plum #dda0dd
complementaryPlum sits directly opposite #99ec69 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Charcoal #36454f
