Sun in sunglasses is also in whatif "Into the sun" and I'm 99% sure this is not the only xkcd appearance of that... --[[Special:Contributions/162.158.86.119|162.158.86.119]] 11:38, 15 September 2016 (UTC)

Why is Randall using JPEG for the second time in a row? Gosh, the comics look horrifying when zoomed in. [[Special:Contributions/108.162.244.67|108.162.244.67]] 12:35, 15 September 2016 (UTC)
:It looks like a .PNG to me, maybe the .jpg was temporary for an upload deadline? [[Special:Contributions/108.162.241.127|108.162.241.127]] 12:54, 15 September 2016 (UTC)
::The one on this page has always been a png file (see [http://www.explainxkcd.com/wiki/index.php?title=1733:_Solar_Spectrum&oldid=127003 the first revision]). This also means that whoever wrote the complaint must have had access to [http://www.explainxkcd.com/wiki/index.php/File:solar_spectrum.png this same file], which has not been updated here since. Of course Randall may have had another version up first, but that seems highly unlikely... --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 14:38, 15 September 2016 (UTC)

Are the spectral lines actually accurate apart from the sunglasses? Wouldn't surprise me to much... (Meh, https://en.wikipedia.org/wiki/Fraunhofer_lines, believably close). [[Special:Contributions/141.101.105.10|141.101.105.10]] 12:51, 15 September 2016 (UTC)

I feel we need an explanation of the concept of spectral lines for those readers not familiar with absorption spectra [[Special:Contributions/141.101.70.91|141.101.70.91]] 13:21, 15 September 2016 (UTC)

I think he's referring to the spectral lines of transition metals - not pictures of the sun wear glasses. The transition lenses reference is a play on words.

:Can we figure out what sunglasses he is referring to by comparing the spectral absorption of different brands? [[Special:Contributions/108.162.246.119|108.162.246.119]] 14:06, 15 September 2016 (UTC)
:Any good links to "permanent" images of a sun with sunglasses? Guess there is none of Wikipedia? --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 14:38, 15 September 2016 (UTC)
:I agree this refers to "Transitions" light-reacting prescription sunglasses / regular reading glasses. However, Google won't give me a sun wearing sunglasses picture unless I type in "sun" and "sunglasses". Not for Transitions or Reactolite, not for weather forecasts, not for emojis. With eyes yes, big smile too, but not shades. I suppose because it actually is a stupid thing for the sun to have. Otherwise, nearest I get: http://www.essilor.com/en/BrandsAndProducts/Lenses/Photochromics/Pages/CrizalTransitions.aspx :-) "30% faster" (than what? taking off the glasses?)

Is there a category for comics without characters? Are there enough comics to need a new category? [[User:GizmoDude|GizmoDude]] ([[User talk:GizmoDude|talk]]) 14:27, 15 September 2016 (UTC)
:There are many many comics without characters, so it would be a huge job to make such a category and they do not necessarily have anything in common like two comics with [[Blondie]] for instance does. So I would say no. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 14:38, 15 September 2016 (UTC)
:"Charts" looks right, seems implicitly to cover "infographics" (btw I agree with worrying about readers who don't know what spectral lines actually are although clearly everyone writing here does, or thinks so). Another possible edition for other cases is "Landscapes" but those in fact tend to have people in (or Mars rovers or such), also landscape in the sense of vista may be covered by "Large drawings" unless that specifically means "Image is larger than the pane on screen", since there also isn't a Scroll it" category. Alternatively... "Spectacles". Robert Carnegie rja.carnegie@excite.com [[Special:Contributions/141.101.98.90|141.101.98.90]] 15:23, 15 September 2016 (UTC)

Ya'll should keep in mind the large number of multivitamins that use rainbows as part of their branding and often some form of spectra/spectrum as part of the brand name. Here's a relevant image: http://centrum.com/sites/default/files/wheel_silver_adults_0.png [[Special:Contributions/173.245.48.65|173.245.48.65]] 17:59, 15 September 2016 (UTC)
:Except Centrum is the only brand I've seen that does that. [[Special:Contributions/141.101.70.61|141.101.70.61]] 08:03, 16 September 2016 (UTC)

There's another image of a Sun with sunglasses (and a giant banana) at http://what-if.xkcd.com/129/ [[User:Jojonete|Jojonete]] ([[User talk:Jojonete|talk]]) 22:59, 15 September 2016 (UTC)

And perhaps we should acknowledge John Finnemore's terrific sketch about J M W Turner painting sunglasses on the sun (transcribed here: http://j-f-s-p.livejournal.com/5403.html). {{unsigned ip|141.101.70.49}}

Given that all the lines for the sunglasses are in the red-orange spectrum I took it as a joke about glasses <a href=https://www.google.com/search?q=orange+wraparound&ie=utf-8&oe=utf-8#q=orange+wrap+around+glasses>similar to these.</a> Sorry I can't find the exact model I've seen in ads from the early 90s of wraparound over regular glasses that were orangish (old style Blue Blockers.)

The idea of the sun wearing transitions lenses became even more silly when I did a little research and found that the silver chloride that they often make transitions lenses with actually has a lower melting point (455°C) than glass itself typically has (1400°C to 1600°C.) I'm not sure that this has any relevance, but I was trying to find a plausible connection between the fabrication of transitions lenses as opposed to standard lenses and the use a sun (a sentient sun) might have for them.
