Mein gott, this color palette IS actually painful to look at. 172.70.178.161 20:02, 3 November 2021 (UTC)
The caption has changed since the image was captured ("color gradient" changed to "color scale"), we need to pull the new comic. Barmar (talk) 20:08, 3 November 2021 (UTC)
- I updated the file, although the changes haven't taken effect yet. theusaf (talk) 20:37, 3 November 2021 (UTC)
Does anyone know what Lambda is often used for in physics (or other sciences) as it relates to Theta, where Theta is phase? 127.0.0.1 20:48, 3 November 2021 (UTC).
- I'm surprised YOU don't know. Wavelength. -- Hkmaly (talk) 22:38, 3 November 2021 (UTC)
- Why are you talking to yourself? 127.0.0.1 21:07, 3 November 2021 (UTC).
- Wouldn't that make this chart self-referential, in that each color output at any particular x,y coordinate can somehow be measured in terms of wavelength and phasing (red shift)? 127.0.0.1 21:17, 3 November 2021 (UTC).
- I think you're responding to my comment (it seems to be above it, though?). Not sure exactly what you mean by self-referential either, but I suppose somewhat. Assuming this is a black body curve, the emission spectra has a peak at the point where the graph shows "peak" intensity; this wavelength is based off the temperature of the black body itself (see Wien's displacement law), whilst the redshift is based on the relative velocity of an observer & the black body (i.e. a star, usually).
- If I had to guess (as an "armchair" astronomer), it seems to be similar to that of a black body (Planck curve) but also showing the phase. A phase shift to me means change in wavelength, i.e. Delta lambda / lambda, but that's normally denoted by the z-parameter (see Wikipedia's redshift article).

Scientific publications aren't the only contenders for the award. I see a Painbow during almost every TV weather report. Captured an image of one of them, hope it displays correctly.
