Greyscale

Hello

After reading an interesting book about behavioural addiction (Irresistible, by Adam Alter, if you're interested), I am looking to alter my desktop to greyscale. I found it makes me more productive.

I can alter my monitor on my main pc. But I was astonished to find my monitor doesn't support this on my home machine.

Is there an easy way to do this with Bunsenlabs?

Re: Greyscale

Easiest way would be to go with a greyscale openbox and gtk theme. Some of the early BL and #! themes may still be available, but I don't have a link for them. You can try gnome-look.org and box-look.org to see if there is something that suits your needs.

Re: Greyscale

I'am guessing there could be a way to generate specific black&white icc (LUT) profile and then load it somehow, possibly poking colord service.

https://wiki.archlinux.org/index.php/ICC_profiles

Bunch of iccs seems to be in /usr/share/color/icc/colord

AdobeRGB1998.icc  BruceRGB.icc       ECI-RGBv1.icc     Gamma6500K.icc   SMPTE-C-RGB.icc
AppleRGB.icc      CIE-RGB.icc        ECI-RGBv2.icc     NTSC-RGB.icc     sRGB.icc
BestRGB.icc       ColorMatchRGB.icc  EktaSpacePS5.icc  PAL-RGB.icc      SwappedRedAndGreen.icc
BetaRGB.icc       Crayons.icc        Gamma5000K.icc    ProPhotoRGB.icc  WideGamutRGB.icc
Bluish.icc        DonRGB4.icc        Gamma5500K.icc    Rec709.icc       x11-colors.icc

edit: Blindly trying

xcalib -d :0 profile.icc

they mostly don't work, Bluish does. Can be due to 'MUST be an ICC profile containing a vcgt or mLUT tag '.

After some experimentation I could not get to change only saturation,  so I'll assume icc is not suitable for that.

In both Helium and upcoming Lithium, use BLOB to switch to a #! desktop (Main Menu>Preferences>BLOB Themes Manager>View Saved>Crunchbang>Restore

You'll be asked if you want to install Faenza icons, go ahead and say yes, you can remove them later.

Then customize from there. Bunsen-Blackish-Remix is still a pre-installed theme, there are Openbox, Notifications and Appearance (gtk2/3) menu entries under "Preferences". Set those, remove the launchers from tint2 and you have something like this...

Re: Greyscale

BTW, I'm amazed and thrilled that my hack themes for helium based on Greybird back then still work in buster with no updating. The shimmerproject does some nice work.

Re: Greyscale

Surprissingly many finds for this.
Seems like changing Xorg configuration is your best bet; the fedoraforum link looked promising.
