Use the Advanced skin tone picker in Roblox Avatar Editor and select black there; many guides say the black option is available through the web/browser avatar editor, especially on mobile, rather than the basic in-app picker.

Quick Scoop

  • Go to Avatar.
  • Open Head and Body.
  • Choose Skin Tone.
  • Tap Advanced.
  • Pick the black color and save/apply it.

What to know

Roblox uses avatar skin-tone colors rather than a single “code” for skin color, so people usually mean the preset black tone in the editor, not a hex code you type in. One catalog result also shows an item named “Color Skin Black,” but for normal avatar skin color, the editor method is the usual route.

Mobile note

Several guides say the Roblox mobile app may not show the full set of tones, so using a browser and requesting the desktop site can expose the Advanced options.

TL;DR

The “code” you want is not really a code; it’s the black preset in Roblox’s Advanced skin tone picker.
