How accurate are these values?
The hex and RGB values are digital approximations from the open-source Ink/Stitch palette files, not physical color measurements. Screens, lighting, dye lots and thread finish all change how a color looks, so check a physical Robison-Anton Polyester shade card before a production run. Match a hex color to thread.
