Can't change fonts or background color on arch

[groovitz]

I typed this in sudo Downloads/matter/matter.py -bg FFF8E1 -fg 263238 -hl E91E63 and this is what was returned

[I] Argument -i required. Which icons go to which grub entries?.
[I] Your grub entries are:
1. Arch Linux
2. Advanced options for Arch Linux
3. Arch Linux, with Linux linux
4. Arch Linux, with Linux linux (fallback initramfs)
5. Windows Boot Manager (on /dev/sda2)
[I] Look for icons you like at https://materialdesignicons.com/
[I] Then install with:
[I] ./matter.py -i icon-for-entry-1 icon-for-entry-2 ...
[I] Example (with 8 entries, _ means ignore):
[I] ./matter.py -i ubuntu microsoft-windows folder _ _ _ _ cog

I tried setting icons and changing background in the same line but it still won't work. Help.

Did you follow through the quickstart? In any case, the only requirement for setting Matter as the error is displaying, is to provide the icons for each of your grub entres (the list with five elements).

You say that doesn't work neither, but could you provide the output when running the command with the -i flag to know exactly what doesn't work?
