What's the wavelength of pure blue?

@atomicrox good point, this can really patch up that WL->HEX/RGB calculator :beer: I would also say true blue is around 463nm

i went with 450. i feel 450 is more of a center shade of blue.

well its good to see (same as me)you said 463nm as i said 460-465nm doesn't get any closer than that ,interesting a few said that 445nm looks quite purple to me its a royal blue color but just a bit darker, its hard to determine actual color because blue lasers put out so much brightness that the spot is basically white its really the beam you can comment on color wise

 

[Atomicrox]

Not to mention colors change depending on the environment. The second laser you turn on always seems to be "pushed" away from the first one. A neutral test should be done in the dark, looking at the beam or defocused dot.

Here's what we got so far:
average: 458.5nm
standard deviation: 9.8nm

Will wait a few more days for more votes.

I wish I had a 455

 

[Atomicrox]

I "measured" my Dominator around 454nm. The color is definitely different from my older C6, much less violet.

Nice curve forming. I guess folks don't like 455nm very specifically

 

[Dr_Evil]

Before reading what others said, I was thinking somewhere around 460 to 465. It seems like many others agree with that range.

 

[Atomicrox]

Yeah, poor 455nm

Results so far:
average: 457.8nm
standard deviation: 9.9nm

I'd have to go with the 460ish. My 445 definitely has a visible purple tint to it. All pictures of a 473 that I have ever seen seem a little greenish, but much closer to what I envision a "true blue".

473nm never looks greenish in the slightest to me. "Shifting" the apparent color doesn't make it look greenish. (Can be done by viewing 445nm or 532nm first, there is an obvious color difference but still blue)

 

[NO4H99]

Well, i'll have to take your word for it, Unless you want to send me that 473 of yours

 

[ZRaffleticket]

Afraid she's not going anywhere

This is really the easiest question
If you ask about science, then there are three main colors which are Red, Green and Blue...
Blue - 475nm
Green - 510nm
Red - 650nm
Everything else is a mix from two of the main colors.
For example Orange is a color with wavelength between Green and Red...
Anything else, that has a different wavelength of the main colors are something else but not the true Red, Green or Blue...
If you get prisma and separate the white light you will receive the three main colors which will have the exact wavelength of 650nm Red, 510nm Green and 475 Blue...

Results so far:
average: 457.4nm
standard deviation: 9.0nm

460nm is starting to lead by a good margin!
Still waiting for more votes, but I guess it's time to open one for green.
