Ubuntu – How to change color profile via terminal commands

color-managementcommand line

I frequently change color profiles from the color settings. I would like to set an alias for convenient switching between color profiles e.g. D50 to D55 and switch back.

enter image description here

Does anyone know how to change via terminal commands?

A.B. answered: double quotes for the ID.

$ colormgr device-get-default-profile "xrandr-Apple Computer Inc-Color LCD"

$ colormgr device-get-default-profile "xrandr_Apple_Computer_Inc_Color_LCD_evn_1000"

List all devices, eg:

$ colormgr get-devices 
Object Path:   /org/freedesktop/ColorManager/devices/cups_HP_Color_LaserJet_CP1514n
Owner:         root

Enabled:       Yes
Embedded:      No
Model:         HP Color LaserJet cp1514n
Vendor:        Hewlett Packard
Serial:        socket://192.168.2.160
Format:        ColorModel.MediaType.Resolution
Scope:         temp
Colorspace:    rgb
Device ID:     cups-HP_Color_LaserJet_CP1514n

Profile 2:     HP_Color_LaserJet_CP1514n-Gray..
Metadata:      OwnerCmdline=/usr/sbin/cupsd -l

and get a profile with

$ colormgr device-get-default-profile cups-HP_Color_LaserJet_CP1514n
Object Path:   /org/freedesktop/ColorManager/profiles/HP_Color_LaserJet_CP1514n_RGB__
Owner:         root
Format:        ColorModel.MediaType.Resolution
Qualifier:     RGB..
Colorspace:    rgb
Scope:         temp
Gamma Table:   No
System Wide:   No
Profile ID:    HP_Color_LaserJet_CP1514n-RGB..

set a profile with:

colormgr device-make-profile-default cups-HP_Color_LaserJet_CP1514n /org/freedesktop/ColorManager/profiles/HP_Color_LaserJet_CP1514n_Gray__

check with:

$ colormgr device-get-default-profile cups-HP_Color_LaserJet_CP1514n
