What they did and found
The system was trained to follow exact hex color codes in prompts to create or edit images. It keeps colors faithful for some objects, but accuracy drops when the scene is complex or objects blend with backgrounds.
Why it matters
Using hex codes can help keep brand colors without extra software, but you must expect some color mismatches in busy scenes.
Training used real color examples that link hex values to objects. The goal is to apply this rule to new images and edits by mentioning the color.
A practical takeaway is that explicit hex codes help color fidelity for simple, localized objects, but precise binding may fail in cluttered or unclear scenes.

What remains uncertain
Color accuracy depends on lighting and scene; linking a hex to a region may fail if the area is unclear.
