Quality to which a unique six-character code is assigned, in graphic design

HUE

Think of the pure, undiluted version of a color before it’s mixed with white or black—what designers often adjust using sliders in digital tools.

In graphic design, "hue" refers to a pure color without added tint or shade—like red, blue, or green—and it’s often represented by a unique six-character hex code (e.g., #FF5733). The clue hints at this by describing a "quality" tied to a code, which in design software or CSS is how hues are precisely defined. The answer plays on the technical side of color theory, where "hue" is the foundational term for color identity.
