More options are in the works as necessary to make the game more accessible.These features and configurations are implemented inside the "AccessibilityTweaks Folder -> Scripts Folder -> main.lua" file for this script. You can open the "main.lua" in Notepad!
At the top of the file you will find lines like so:

-- Disable the eat icon for pals who are working in your bases. There is no current way to "stop it animating" at this time.
local animDisableEatIcon = true
-- Disable the sleep icon for pals who are working in your bases. There is no current way to "stop it animating" at this time.
local animDisableSleepIcon = true
 
local enemyColor = {
    R=0, 
    G=255, 
    B=195, 
    A=1.0
}
local friendColor = {
    R=255,
    G=255, 
    B=255, 
    A=1.0
}
local palXPColor = {
    R=255,
    G=255,
    B=255, 
    A=1.0
}

Simply change the "true" to a "false" if you do not want the option enabled, or change the R, G and B values (the part after the equals sign) to be more to your liking.
YOU MUST RESTART THE GAME TO APPLY CHANGES!
You can find sites like: this one that provide color pickers
The site above will provide you with the R, G and B values for colors of your choice. If the color turns white, it may not be supported in Palworld. Please leave "A" as 1.0 unless you know what you are doing.
Currently, there is no way to change the text color (yet).
