    ArcGIS Pro style (.stylx)

    A continuous ramp made of 16 colors joined by CIELAB segments, so lightness stays linear in ArcGIS Pro. To use it in Pro, open Catalog → Styles, right-click and choose Add → Add Style, then pick this file. The ramp then appears in the Symbology pane's color scheme list (turn on Show names and Show all).

    QGIS style (.xml)

    A gradient color ramp with 32 stops. In QGIS, open Settings → Style Manager, choose Import/Export → Import Item(s), pick this file, select the ramp and click Import. It then appears in every color ramp menu.
