Is this the shortest wavelength that your computer/phone can emit? Most devices are equipped with monochromatic red light, green light and blue light, and mixed together to make the rest of the spectrum, would that mean that pure blue (#0000FF) is the shortest wavelength you can emit?

yes, violet has a shorter wavelength than blue but our computers aren't equipped with it, for good reason, the shortest wavelength colors tend to be harmful to the eyes, the blue you posted in picrel is probably borderline until it get unsafe for the eyes

It's probably easiest to visualize the case where you have blue, red and green subpixels. The bluest you can get from a given display (presumably corresponding to that hex code) is when only the blue pixels are on.
The wavelength of this will depend on what the material in the pixel is. Off the top of my head, I think the emission peak will likely be around 430-450 nm. Real emitters also have a finite emission spectrum width, and the purity of your blue depends on how broad the emission spectrum is (more broad = less pure colors).
There are different display technologies out there, but the general idea will be similar.

There's all kinds of issues with deep-blue and especially UV LEDs, and while eye safety may be among them the main problems are technological.

There is no way that is true.

Blue light is not harmful to the eyes. If it were, blue-light receptors on the retinas would've been naturally selected out of the species ages ago.

This guy doesn't understand how light and evolution works

You are the blessed retard. Fish spend all their days in blue light environment and somehow their eyes are fine

How come this board never discusses whether red light can hurt your eyes?

Red light conspiracy. They don't want you to know.
I already said too much

Because it's a known fact that Red carry the least photon energy out of all colors and is thus the least harmful
It is ironic, how the color of passion is actually the most chill to our eyes and the color of calm bother our eyes the most
