Wheat colored Bamboo safe?

[Julopy]

Hi dear community, well after reading good stuff about cotton and bamboo wicks i decided to give bamboo a try and ordered this
Amazon.com: Aunt Lydia's Bamboo Crochet Thread Size 3-Wheat: Arts, Crafts & Sewing at the time i ordered it didn't have the color options and it seemed a "natural" color. I received my order today and for my surprise it reads ART.147 WHEAT in the back.

Would it still be safe to wick?

thanks in advance
