The "particular set of words" is obviously "My voice is my passport. Verify me."

If it isn't, they need to reconsider this whole idea.

Hypercolor ink and dye didn't change color. It just disappeared and revealed the color underneath. It could never be made opaque enough to cover anything completely so the colors combined. They also had photocromic dye and ink that reacted to light but it had the same limitations. Everyone wanted the type of changes you describe but all you could get was orange to yellow or green to blue.

It is hard to believe the millions of dollars and hundreds of jobs that came and went in a flash here in Seattle. It was supposed to be the thing to save Generra but it just made the end more spectacular. The old ATT building at Denny and Broad was filled with hundreds of employees when hypercolor started and several years later the company only consisted of the two owners, a lawyer and an accountant who successfully licensed the name Generra to other clothing companies.

Thanks for the concise and definitive history of Generra. It could be about a lot of different local companies.
I could never justify a shirt that matched my mood because all my tshirts are already black.

@5: +100 for that. I miss Ealing Studios.

What a weird application for that technology. In that scenario they described, my first thought was the scene in Antz where they first encounter plastic wrap.
