I am looking for a nice and simple way to adjust screen colours. Redshift seems to do it so it is certainly possible. Is there a utility which gives some Red, Green, Blue scroll bars to adjust screen colours? So far what I have found (colormgr, Argyll CMS) all look too complicated to use and can't get my tiny head around those.
I have Ubuntu 14.04 installed on a HP pavilion laptop.
Thanks, Deepesh PS: I can handle terminal so command line tool will do if the options are simple as -r -g -b.
Use xcalib
usage: xcalib [-options] ICCPROFILE
or xcalib [-options] -alter
where the available options are:
-display <host:dpy> or -d
-screen <screen-#> or -s
-clear or -c
-noaction <LUT-size> or -n
-verbose or -v
-printramps or -p
-loss or -l
-invert or -i
-gammacor <gamma> or -gc
-brightness <percent> or -b
-contrast <percent> or -co
-red <gamma> <brightness-percent> <contrast-percent>
-green <gamma> <brightness-percent> <contrast-percent>
-blue <gamma> <brightness-percent> <contrast-percent>
-alter or -a
-help or -h
-version
last parameter must be an ICC profile containing a vcgt-tag
Example: ./xcalib -d :0 -s 0 -v bluish.icc
Example: ./xcalib -red 1.1 10.0 100.0
Use the xgamma module to adjust gamma values across RGB.
usage: xgamma [-options]
where the available options are:
-display host:dpy or -d
-quiet or -q
-screen or -s
-version or -v
-gamma f.f Gamma Value
-rgamma f.f Red Gamma Value
-ggamma f.f Green Gamma Value
-bgamma f.f Blue Gamma Value
If no gamma is specified, returns the current setting
In settings -> color you should be able to change the color settings of your monitor. Can not find what you need?
