Shoutout to the avant-garde brands using algae-based dyes, but are we sacrificing color fastness for eco-points?

I was at a pop-up show last week and fell in love with a vibrant scarf dyed with algae pigments. Proponents say it's a game-changer for cutting water pollution from traditional dyehouses. Critics argue these colors fade faster, turning statement pieces into disappointments after a few washes. It's got me debating whether temporary beauty is worth the environmental gain. Where do you all stand on prioritizing longevity versus sustainability in fabric treatments?
