Colored Liquid Ink Set

Colored Liquid Ink Set: What It Is and Who It Serves

Colored Liquid Ink Set (SKU GMO-LIQ-005) is an 8-color set of 30ml liquid ink bottles formulated from mineral-based pigments with a natural binder — vermillion, ochre, azure, green, purple, white, gold, and silver. Every color is filtered and tested for concentration consistency, and the set carries a tested lightfastness rating of grade 4+ under ISO 105-B02: the pigments resist fading when displayed rather than washing out within months.

This product is built for painting studios, art supply distributors, and cultural gift programs that need color results their customers can rely on across batches — not a palette that shifts shade every reorder. Each shipment includes color reference charts and lightfastness test reports, so the color standard you approve at sampling is the standard documented in your bulk order. If color stability is what you are buying, this page sets out what is confirmed and what to confirm with us before ordering.

The Sourcing Problems This Set Is Built to Solve

Problem 1: colors that fade on display. Cheap colored inks use dyes that bleach under light, so paintings displayed in bright studios or shop windows lose their color within a season. This set uses mineral-based pigments with a tested lightfastness grade of 4+ (ISO 105-B02), and the test reports ship with every order.

Problem 2: color drift between batches. Reordered ink that arrives a different shade forces studios to repaint, retest, or write off stock. Each color is filtered and tested for concentration consistency, and color reference charts are included per shipment so batch-to-batch color can be verified against a documented standard.

Problem 3: suppliers who cannot match a specific color need. Many programs need a shade that is not in the standard palette. We offer custom color matching from buyer reference artwork, run from our pigment testing lab and color-matching station.

Specifications

Why Mineral-Based Pigments Change the Purchase Decision

The pigment base is the single biggest differentiator in colored ink, and it is the property most often hidden in supplier listings. Dye-based inks look identical in the bottle but bleach under display lighting; mineral-based pigments hold their color. For a distributor, that difference decides whether customers come back for a second set or return the first one. For a studio, it decides whether commissioned work still looks right when the client hangs it. This is why our QC chain tests pigment concentration per color and the lightfastness rating against the ISO 105-B02 standard — and why the reports are included rather than available on request. The 8-color palette covers the traditional gongbi and gongbi-adjacent ranges, including the metallic gold and silver used in decorative work and the white needed for highlights and mixing.

How Quality Is Verified per Batch

• Pigment concentration test: each color is filtered and tested for concentration consistency, so the same color name delivers the same strength from one order to the next.
• Lightfastness test: the formulation is tested to grade 4+ under ISO 105-B02, and test reports ship with every order.
• Color reference charts: included per shipment so buyers can verify received color against the documented standard.
• Safety compliance: pigments meet ASTM D4236 safety standards — the baseline institutional and retail buyers ask for.

Custom Colors and Private-Label Packaging

Beyond the eight standard colors, we offer custom color matching from your reference artwork, run through our color-matching station — used by studios with a signature palette and by distributors differentiating their line. The set ships in a presentation gift box with private-label option: custom gift box design and label printing carrying your brand, which is how the Vietnam distributor case below built a premium painting supply line on this product. MOQ is 50 sets, low enough to pilot a private-label run before scaling.

Because formulation, testing, and color-matching run in-house, the lightfastness reports and reference charts in your shipment trace back to the batches tested on our own floor.

Delivery Reference: A Vietnam Distributor Order

An art supply distributor in Vietnam ordered 300 sets of colored liquid ink with custom branded packaging for a premium painting supply line. Color reference charts were provided within 10 days, production was completed in 38 days, and the shipment went out with lightfastness test reports. The distributor reported consistent color quality and reordered for the next season.

Where Buyers Have Seen This Set

The Colored Liquid Ink Set was displayed at the China International Cultural Industries Fair and the Vietnam Art Materials Expo. Visitors examined the color reference charts and requested custom color matching for studio use — the same workflow we run for buyer inquiries today.
