Brownstone is not a common color name. The Color Guild color collection has a paint color named Brownstone. Smaller paint manufacturers buy memberships to color collections/palettes. The Color Guild (Columbus, Ohio) is one of those color palette membership organizations.

This could be a guild color. Sold under "The Colorizer" color brand name and found in stores like Diamond Vogel, Rodda Paints, Graham Paints, Miller Paints, Kelly Moore, etc.

Couple possibilities. Have the name right, but number isn't a color number rather it's about something else. Or, it's a number that's unique to the store where the color was purchased.

Thank you, funcolors, for the info. I will look into it.

Regards,
