更环保的墨水诞生了！不用石油，用海藻

Inks, paints, pigments, and dyes have come from the natural world for centuries.

数百年来，墨水、颜料、涂料和染料都来源于自然界。

在文艺复兴时期，天青石被磨制成鲜艳的深蓝色颜料，胭脂虫被制成深红色颜料（现在依然如此）；铜和铅等矿物质被制成绿色颜料；而黑墨水则是用由碳衍生的烟煤和炭制成的（你猜怎么着，目前我们依然用石油化工产品制造颜料）。

用颜料和亚麻籽油或蛋黄等粘合剂可以制成油漆。

Chemical innovations in the nineteenth century produced the likes of viridian green, cadmium orange, and chrome yellow.
