Veins in near infrared light

Me too. But that's cool about the HI thing

I have no idea what could have been said about this that could be hated to the point of deletion.

No. It doesn't work like that.
The human eye can not see near infared. The display must use spectra that our eyes can see... consequently, it can use ANY color.
In this device, the machine is protecting what it "sees" where it sees it... onto the skin. Green is used to contrast against this persons skin tone.

Actually infrared is portrayed as green because our eyes can see more shades of green than any other color. Therefore the shades of green are basically a glorified gray scale that our eyes are able to differentiate better. (same reason night vision goggles are in green)

That too actually... I think we're both right. But yes, the human eye is the most sensitive to the green portion of the visible spectrum.
