This right now is just a place to store ideas

I don’t have is a ready-to-go lesson that has, say, lists of members of clusters of a variety of ages which you could use similarly to get Gaia CMDs that you could, say, put in relative age order. You could, with some effort, take the data from here: https://ui.adsabs.harvard.edu/abs/2018A%26A...616A..10G/abstract And extract the source list (cluster, ra, dec) for each star from the relevant tables http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/616/A10#/browse Separating them out into one source list per cluster, in the right IPAC table format. Then bounce that ra, dec against IRSA’s copy of the Gaia catalogs to get G, B, and R, then use that to make the CMDs.

do the same thing against 2mass and explore why the NIR CMDs look so different than the optical ones.
