Quick answers before the detail: Nail polish is Class 3, not Class 2 — Class 2 covers paint applied to objects and surfaces, not skin or nails. Raw pigment chemistry is Class 1; a finished, ready-to-use paint or coating is Class 2. Owning a specific color as a trademark is possible but rare, and it's a separate legal question from registering a paint product.
Nice Class 2 covers the point where chemistry becomes color: paints, varnishes, lacquers, and protective coatings; pigments and dyes; primers and undercoats; anti-corrosion and wood-preservative preparations; and, in some cases, printing inks and toners. It's downstream from Class 1's raw industrial chemicals, and its products are meant to go on something — a wall, a car body, a fence — rather than be consumed, worn, or applied to skin.
The Finished-Product Line
The class turns on one distinction: finished product versus raw input. A resin or industrial chemical waiting to become paint is Class 1. Once it's a ready-to-use pigment, varnish, or coating, it's Class 2. Manufacturers who produce both the underlying chemistry and the finished coatings — and there are many — end up filing in both classes; our Class 1 guide covers the raw-input side of that relationship.
A second line matters just as much and trips up more people: art and craft materials. Artists' paints can sit in Class 2 as colorants, but crayons, writing inks, and most stationery-adjacent art supplies are actually Class 16. There's no single rule of thumb here — it depends on the specific product, so a brand selling both house paint and children's craft sets should map each item rather than assume one class covers the range.
Sherwin-Williams, Pantone, and the Business of Color
Few classes are as directly about color as this one, which is why some of the most recognizable Class 2 names are built entirely around color authority. Sherwin-Williams and Behr anchor the consumer house-paint side of the class with deep portfolios; automotive and industrial coating brands cover specialty finishes; and Pantone occupies a stranger niche — its color-matching system is a globally recognized standard that design and manufacturing industries treat as a reference point, not just a product line.
That leads to a separate and much harder question: can a brand own a specific shade as a trademark, distinct from any paint product it sells? It's legally possible but rarely succeeds — you have to prove the color is non-functional and has acquired distinctiveness in consumers' minds. Most attempts fail. Our guide on whether you can trademark a color walks through what evidence actually clears that bar.
Filing Mistakes That Keep Recurring
Founders in this space tend to make the same handful of errors: filing raw industrial chemicals in Class 2 instead of Class 1, filing nail polish here instead of Class 3 (a beauty-brand assumption that "polish" and "paint" share a class — they don't), misplacing art crayons that actually belong in Class 16, and single-class filing when the catalog genuinely spans chemistry and finished coatings. None of these are hard to catch with a careful goods description before submission.
