Suggestion for X-axis: red - yellow - green - blue (like visible light spectral colours, but in reverse direction)

Suggestion for y-axis: 62 (red) - 159 (yellow) - 187 (blue) - 205 (green) - 230 (blue)

If the second "graph" really is a representation of the same data as the first, there should be five points, corresponding to (approximately) {(17, 62), (36, 159), (67, 206), (88, 186), (100, 232)}. I copied the first plot to GIMP, cropped it, scaled it to 100x250, and measured the centres of the dots. :-) BunsenH (talk) 02:19, 7 December 2023 (UTC)

I agree with five labels. Combining these information above so far, and adding information from the Color Model HSV (also extracted with GIMP, from the large file :-)

17, 62, hue 13 (red, HEX ff3a00)

36, 159, hue 51 (yellow, HEX ffdb0f)

67, 205, hue 87 (green, HEX 8afc03)

88, 187, hue 169 (turquoise, HEX 08a387)

100, 230, hue 217 (blue, HEX 0060ff)

Does anyone find a consistent/proportional correlation between x-axis and HSV-hue? If not, it makes not much sense to mention the x-axis values in the explanation.

Sorta! It lines up with the x values for 3 of them and the y values for 2 of them, which is unlikely to be a pure coincidence. Attempted to explain all this in my edits just now. Laser813 (talk) 20:32, 7 December 2023 (UTC)

Should we link to 2537: Painbow Award Kvarts314 (talk) 10:43, 7 December 2023 (UTC)

Added it. Laser813 (talk) 20:32, 7 December 2023 (UTC)

I think we're still missing the joke. In graph theory, there's a number of important problems and theorems related to colouring and to compact graphs (although I don't think many problems involve both concepts). Someone better versed in graph theory should chime in. 15:27, 7 December 2023 (UTC)

I personally don't think it goes that deep, but I'm not a graph theory expert. Laser813 (talk) 20:32, 7 December 2023 (UTC)

Perhaps someone better at graphics than me could create a "key" for the Hue-Label graph, showing how the colors from 0 to 360 hue correspond to numbers? Laser813 (talk) 20:32, 7 December 2023 (UTC)
