Technically, on UNIX, ':' is valid in a filename. Filename examples which contain ':' on my Fedora 29:

/usr/share/man/man3/List::Util.3pm.gz
/usr/share/usb_modeswitch/0408:f000
/proc/irq/127/ahci[0000:00:17.0]
/proc/irq/131/snd_hda_intel:card0
/dev/block/259:3
/sys/kernel/slab/:0002632
/sys/module/psmouse/drivers/serio:psmouse

Note: I cannot find a program name which contains ':'.
