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)
