Just wanted to point it out, I'm glad someone already noticed it. Besides I think that's not just salt, it looks like multiple kinds of spices. It could be dyed salt, but I don't really see a sensible reason to buy salt and dye instead of just buying spices.
Which would, in my opinion, still cost more than the spices, because I've never seen such coloured salt in my life, so I assume it's rare. Maybe I'm wrong and I just never noticed this coloured salt, but to me it just seems that getting spices would be a lot cheaper and easier.
Besides, have you noticed how bright some of the colours are? I don't think it's just naturally coloured salt.
Well the point is, why the heck would you bother getting some rare pink Himalayan salt for one pic of the galaxy when you can just buy other spices? That's what kinda messes with my head since the title says "with salt" and I don't really get if there's a mistake in the title or if someone actually got special salts for this.
They're really not that rare. Salts are colored through various elemental impurities and they can be found abundantly in various locations. The pink himalayan salt is from Costco for example. I think they also have blue from somewhere else (and white obviously).
