Does anyone knows if it is possible to manually modify SAGA GIS colour palettes, for example using ColorBrewer references?

  • How have you modified your SAGA palettes so far? – user30184 Dec 2 '16 at 11:58
  • Yes, manually, but I was asking if I can put the colorBrewer palette codes. I've been seeing SAGA GIS help, and it should be a way, but I did not find it...Thanks for answering @user30184 – user66349 Dec 4 '16 at 8:35
  • Could this article be helpful marinedataliteracy.org/grids/colscripts.htm? – user30184 Dec 4 '16 at 11:14

Overall Workflow

  1. Download ColorBrewer RGB color list
  2. SAGA - Colors - Lookup Table - Save .pal
  3. SAGA - Colors - Graduated Colors - Load .pal

First, I visited ColorBrewer2 website, and downloaded one of its Excel sheet. I chose 6 colors of Orange-Red sequence. (a part of sheet as below)

Second, I opened SAGA and loaded a DEM file. At Colors section, I started with Lookup Table and manualy set RGB codes into each 6 palettes.

After entering all colors, I pushed Colors button.

Then changed numbers of colors by Counts from 6 to 24. This palette was stored as .pal file.

Third, going back to Colors section, I changed the type from Lookup table to Graduated colors. And Loaded the color palette of 24 colors I have just saved. Then pushed Apply.

Below is outcome.
