I have been trying to launch a script of mine at start-up using both rc.local and crontab methods but neither are working

Here is my script contents:

#!/bin/bash

sudo hue spectrum 2

exit 0

Here is my crontab contents (minus the comments):

@reboot /home/ben/Documents/startup_scripts/hue+.sh

EDIT:
I tried using the echo command to simulate me typing in my pass word in one line but alas, that did not work either.
Here is that version of the script:

#!/bin/bash

echo <mypassword> | sudo -S hue spectrum 2

exit 0

EDIT 2:
I do use the sudo crontab file and the hue command starts an open source version of NZXT's CAM software that lets me control NZXT devices in my computer (cooler, fans, LEDs, etc) also here is the "hue.log" file for those who have asked for it

/home/ben/Documents/startup_scripts/hue+.sh: line 2: hue: command not found

I don't know hwy it says command not found this command 100% works with sudo

EDIT 3:
I added myself to the group "dialout" and now the command works without sudo, unfortunately the log file is identical to what it was before and the script still does not work on startup

/home/ben/Documents/startup_scripts/hue+.sh: line 2: hue: command not found
