I'd like to get a colour scheme gradient (e.g. ColorData["TemperatureMap"]), split the domain into n equidistant points, and then recover the colour codes (RGB or Hex) for the resulting n points.

  • $\begingroup$ Browsing this site, it seems the goal is always to avoid using Table. In that spirit, this does the same thing: List @@@ ColorData["TemperatureMap"] /@ Subdivide[1, 10] $\endgroup$
