In this video I’m testing Daniel Smith Manganese Blue Hue and digging into what’s really giving it that bright, “glowy” look. I swatch it out, compare how it behaves in a wash, and talk about the hidden ingredient vibe—because this color is one of those that looks simple until you start asking why it’s doing that on paper. I also touch on the Daniel Smith Primatek controversy and why it matters to me as someone who cares about pigment info, labeling, and what we’re actually buying. Then I show you how I mix my own versions of two popular Primatek mineral colors: Blue Apatite Genuine and Lunar Blue. I walk through the mixing approach I use to get that mineral/granulating texture and the overall color impression without needing the exact tube. I also added a science note: I likely misspoke when I said “refract” in the video—what we’re seeing can be fluorescence under UV (like an optical brightener/resin effect). Either way, the takeaway is that the visual effect is real, and understanding what causes it helps you choose (or mix) colors more intentionally.
