here is my script for adjusting screen temp as the time changes.

What are some of your scripts or reasons for doing scripts?
e, the values im adjusting still.  probably the day time values will be adjusted to be cooler.

#!/bin/bash
# Check if xsct is installed
if ! command -v xsct &> /dev/null
then
    echo "Error: xsct not found."
    exit 1
fi

# Retrieve the current hour (0-23) and adjust the temperature accordingly
current_hour=$(date +%H)
current_min=$(date +%M)

while true; do

new_temperature=4000

if (( $current_hour < 12 )); then
if (( $current_min < 14)); then
    new_temperature=6500
elif (( $current_min < 29)); then
    new_temperature=6400
elif (( $current_min < 44)); then
    new_temperature=6300

    new_temperature=1350

fi
# Call xsct to adjust the screen temperature
echo "Adjusting screen temperature to $new_temperature K."
xsct $new_temperature
sleep 150
done

Added later 10 h 47 min 04 s:
there is an edit to under the line "if (( $current_hour < 12 )); then"

it should have a line that says "new_temperature=6500"

Re: here is my script for adjusting screen temp as the time changes.

So I'm not the only one who write scripts to solve daily stuff. When I installed linux I had to deal with a really headache problem that hurts my eyes when I stare at my screen and I made a temp fix. But now since I put the script as part of a startup program I run every time I logon xfce, now it does the job for me.

For all the adjustments, I used my phone white screen as a reference, searched for a color picker, and then picked a color that looks as white/gray as my phone screen, and then calculated the percentage of rgb values I had to reduce to get the desire "white" I wanted my screen to me, later added the loss contrast back resulting on the first xcalib command. Now the temp fix turned permanent but later I might use a more proper method. The fix took me around 2 hours to make. At least it stopped my eyes from bleeding 

xcalib -green 0.6 0.0 90.0 -red 0.6 0.0 92.0 -blue 0.6 0.0 99.0 -alter
xcalib -gc 1.5 -a

echo "Monitor adjusted. To reset enter xcalib -c"

Another one specifically for Arch linux that got me adding a lot more code than I imagine. Because the invert screen script (xcalib -i -a) undid itself once I used xrandr. The only minor problem is it retains the previous invert/not-invert status and might invert the screen even I did not tell it to. But it's easily fixed with a cntl-alt-i, which is my invert script

#!/bin/bash

# ###############################################################
# Script to adjust brightness of the monitor
# Note1: This script is designed as a workaround for arch linux's
#        weirdness
# Note2: Make the file ~/isinvert for the script to action
# ###############################################################

# -- exit if brightness is too bright or dim --

# value is given in decimal form but only integer comparasion is available
brightnessValue=$(echo "scale=0;$1*100/1" | bc)

if [ $brightnessValue -gt 111 ]; then
    echo 'Value not set: Too large. Might whiten the screen'
    exit 1
elif [ $brightnessValue -lt 14 ]; then
    echo 'Value not set: Too small. Will dim the screen too much. '
    exit 1
fi

# -- reset xcalib and adjust brightness --
xcalib -c &> /dev/null
xrandr --output eDP-1 --brightness ${1} &> /dev/null
~/Desktop/adjust-xcalib.sh &> /dev/null

# -- script for restoring screen if it's inverted --
isinvert=$(cat ~/isinvert)

if [ $isinvert = 'true' ]; then
    xcalib -i -a &> /dev/null # re-invert the screen after its resetted
else
    echo 'screen not inverted beforehand so nothing is done in here' > /dev/null
fi

Edit: forgot the invert script

#!/bin/bash

# -- script to invert display and also save it to a file --

isinvert=$(cat /home/js/isinvert)
echo 'isinvert='$isinvert

xcalib -i -a
if [ $isinvert = 'false' ]; then
    echo 'true' > /home/js/isinvert
else
    echo 'false' > /home/js/isinvert
fi
