It is based on xrandr's gamma correction and brightness adjustment.  As such, it can only be used for X displays and not Wayland displays.  It is typically used for tuning the color balance and color temperature.  \n\nIt has a similar function as `redshift -P -g R:G:B -O temperature`, but `xwhite` is more flexible in that it does not keep the white color fixed, suitable for setting the white color to an arbitrary balanced color.\n\n## Usage\n\n```\n// xwhite --output \u003coutput\u003e --rgb \u003cR\u003e:\u003cG\u003e:\u003cB\u003e\n// R G B {0-1}, normalized, mapped to gamut, logrithmic\n//       (sRGB primaries and gamma correction)\nxwhite --output LVDS-1 --rgb 1.00000000:0.71976951:0.42860152\n// 3000K color temperture.\n```\n\nReference for white color normalized RGB value regarding to color temperture: https://github.com/jonls/redshift/blob/master/README-colorramp.\n\n## License\n\nGPL-2.0-only license no later versions.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farstgit%2Fxwhite","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Farstgit%2Fxwhite","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farstgit%2Fxwhite/lists"}
