Warm and slightly sour, like rhubarb tart served next to a bowl of quince. Eosine Pink brings a clear, sugary pink, while Citrine is a mustardy, olive-tinged yellow of almost identical lightness, so nothing separates them but hue. Text is out of the question. Patterned packaging is where they shine: a jam label, a gelato tub, or spring wrapping paper at a florist.
