pixd is a tool for visualizing binary data using a colour palette. It is in a lot of ways akin to a hexdump tool, except using coloured squares to represent each octet.
pixd uses 24-bit color SGR escape sequences. For a list of terminal emulators with support for these, see XVilka's list of supporting terminal emulators.
