=== Colors ===
The colors of LTO Ultrium cartridge shells are mostly consistent, though not formally standardized; HP is the notable exception. Sometimes similar, rather than identical, colors are used by different manufacturers (slate-blue and blue-gray; green, teal, and blue-green; dark red and burgundy).
