I strongly disagree with the explanation's assertion that the peak in the large spectrum, the fire, is the 4.3µm CO2 emission listed in the source given. The peak in the source's spectrum is clearly outside of the near-infrared spectrum and it is just as clearly on the long wave side of the black-body peak in the chart. The comic doesn't even show these wavelengths at all. If, as it appears, that the chart in the comic is a semi-log plot, then the peak is roughly in the 1,000~1,200nm range.[[User:ExternalMonolog|ExternalMonolog]] ([[User talk:ExternalMonolog|talk]]) 01:20, 26 December 2013 (UTC)ExternalMonolog | I strongly disagree with the explanation's assertion that the peak in the large spectrum, the fire, is the 4.3µm CO2 emission listed in the source given.

If I am reading the graphs right, except for the very top there is no blue lights. From the guy with his eye on the sky. (talk) 06:41, 25 December 2013 (UTC)
Presumably the top is gold? 173.245.52.211 07:47, 25 December 2013 (UTC)
Also the spike in the near IR of the large graph is likely to be a mercury line. I think fires would have a smoother curve of a black body. 199.27.128.122 06:47, 25 December 2013 (UTC)
Could someone make a coloured version?Guru-45 (talk) 07:22, 25 December 2013 (UTC)
Also the light at the top of the tree seems to be emitting in the UV range. Perhaps it’s supposed to be a fluorescent lamp? 108.162.245.7 07:30, 25 December 2013 (UTC)
I'm thinking it's a "white" LED. 108.162.216.56 07:50, 25 December 2013 (UTC)
I think the one at the top matches the profile of a star... 141.101.99.211 08:18, 25 December 2013 (UTC)
The spike is not in the "near" infrared, this is water and/or carbondioxide line. 108.162.231.214 (talk) (please sign your comments with ~~~~)
From a rough pixel-measurement and assuming a linear scale, the peak on the large spectrum is at around 800 nm. I'm not sure what to make from the peak, but infrared light is heat radiation, so it could be the representation of sharing warmth and love. 15:15, 25 December 2013 (UTC)
The top spectrum closely matches that of a cool-white LED. The strong peak in the blue, the broad peak from red to green, and the dip in the cyan range is a real give-away. Exactly like LEDs.ExternalMonolog (talk) 01:00, 26 December 2013 (UTC)ExternalMonolog
