- Etheryte 6y agoThis only makes sense on a precisely calibrated display. On everything else, there's no way to tell what wavelength you actually end up with when you fill your screen with a color.
- contravariant 6y agoA perfectly calibrated display might still not be able to display pure wavelengths. At the very least if it's calibrated properly it won't normally do so at #ff0000 as pure 670nm is well outside the sRGB colour space.
- andy_ppp 6y agoI imagine the brightness of a monitor is not enough for there to be any effect but maybe I'm wrong?
- liziwizi 6y agoyes but when i drag the slider i see that 645-700nm is also ff0000. i don't know how precise it should be..
- rbanffy 6y agoI would assume one needs a very good laser+DLP projection system to make this work.
