Just reading the article, it's kinda double-backwards to be the right way again: It works by turning OFF the negative colours. The pigments go transparent when lit up with their specific colour freq. You produce blue by turning the yellow dye transparent - which leaves just the magenta & cyan dye remaining in the mix (this gives you blue). So on it's own, seems kinda weird but the yellow pigment is turned transparent by blue light (then UV light will turn it yellow again).
Reminds me of the scene in Total Recall where Quaid goes into the Rekall office and the receptionist is changing the color of her nails instantly by touching them with a pen-like device.
Pretty impressive. I wonder how much time it takes to erase the pattern in sunlight(which include visible light and UV both). It took about few hours to make pattern, and it took only 10 minutes to erase whole pattern with the UV machine. And I'd like to read your paper, but that doi address doesn't exists now.
I would be more worried about the necessary wavelengths to "paint" the colours. It all was done in pretty dim rooms and with light that seems to be visible around us, I wouldn't be surprised if this is just a mess within half an hour anywhere...
The doi address didnt work? Anyway in the MIT News article it said "The color remains, even when used in natural environments." Does this mean the color will not fade with prolonged exposure to the sun? I would imagine that the direct UV light from the coloring process is much stronger than indirect UV from the sun.
This would require an electrically controlled UV blocking top layer or some other mechanism to prevent the effects of UV light on the ink. Otherwise fading or other tampering like UV “keying” so to speak by malicious parties to put dicks and swastikas on your car. Super cool project though.
There is no expiration time for the product??? ,,, I think it doesn't stay for long and the color level is poor. For sure it needs a lot of improvements.

Fantastic! What a brilliant idea! I am completely excited about it!
AWESOME ! Any price range ?!

the future is here.
Sensacional... muito impressionante!
oh great, now we get RGB everything now

what about this thing used as tattoo spray? If it could do that. people can easily erase their “tattoo” by being exposed to uv light.

This is right out of back to the future
Parabéns muito top
Raves are gonna get so lit
Amazin!
Gonna see new E ink Display ?
The red is not working well
YESSS!!!
Mantab...
Glow in the dark?
The “cyan” dye you used is not at all cyan. It’s primary blue.
о да, представляю какие будут дорогие предметы с этими чернилами

Environmental impact?
Nothing jumps out at me as environmentally impactful. Did you see something that made you think of that

This is Cyberpunkish... :)
Quien vino por un poco de todo?
Keep this far away from Anish Kapoor.
