What are some black codes?

Some black color codes in common color systems include hex codes used for web and design. Pure black is hex #000000 with RGB 0,0,0, which is absence of light. Off blacks include #0A0A0A very dark gray near black, #1A1A1A dark charcoal, #2B2B2B dark gray black, and #121212 often used for dark mode backgrounds. Other named black codes include #0B0B0B, #101010, and #1C1C1C for soft blacks that are less harsh than pure black. In fashion and paint, blacks have codes like Jet Black #343434, Ebony #555D50, Onyx #353839, Obsidian #0B0B0B, and Raven #0B0B0B. In Pantone, black is Pantone Black C or Pantone Black 6 C for deep black. In CMYK for printing, rich black might be 60 40 40 100 to get deeper black than 0 0 0 100. For design, pure black can be too harsh, so designers often use very dark grays like #111111 or #1A1A1A as softer black alternatives that are easier on eyes while still appearing black.
