Colored Hui Ink Stick Set

The Color Problem in Traditional Chinese Painting Supplies

If you supply painting studios, museum shops, or cultural gift programs, you have probably heard the same complaints about colored ink sticks: pigment concentration varies between batches, colors fade after months on display, and some sticks simply do not adhere well to Xuan paper — the surface most traditional painting depends on. For a professional studio, an inconsistent color set is not a minor annoyance; it ruins finished work and the studio's trust in your brand.

The root cause is formulation discipline. Colored ink sticks are made from mineral pigments bound with natural binder, and without per-batch testing of pigment concentration and adhesion, every production run becomes a lottery.

The Colored Hui Ink Stick Set (GMO-HIS-003) was built to remove that lottery: a five-color set formulated with mineral pigments of tested lightfastness, batch-tested for concentration and adhesion before packaging, and shipped with a color reference card so your team — and your customers — can verify color accuracy against a documented standard.

The Five-Color Palette and Why It Is Built This Way

The set contains vermillion, ochre, azure, white, and yellow — five colors that together cover the core palette of traditional Chinese painting, from flower-and-bird subjects to landscape accents and figure work. Each stick weighs 20 grams, and each set contains 5 sticks, giving studios a workable supply of each color without forcing them to buy singles of shades they rarely use.

The formulation choices behind the set are deliberate:

• Mineral pigments with natural binder — mineral pigment is the traditional basis for stable color in Chinese painting; the natural binder keeps the stick grinding smoothly on an inkstone and adhering to Xuan paper.
• Tested lightfastness grade 4+ (ISO 105-B02) — the color performance against light exposure is not claimed from a catalog; it is tested. Grade 4 or higher means displayed work keeps its color far longer than fugitive pigments would allow.
• Per-batch pigment concentration and adhesion testing — every color batch is tested for pigment concentration and adhesion before packaging, so batch-to-batch consistency is checked, not assumed.
• Safety documentation — all pigments meet ASTM D4236 safety standards and are tested for heavy metal content, which matters for education channels, museum programs, and any buyer who must answer safety questions from their own customers.

Custom Color Matching from Your Artwork

The five standard colors cover most traditional painting needs, but institutional collections, museum editions, and branded gift programs often need something specific — a museum's house vermillion, a commemorative shade, or a color set matched to an exhibition theme.

Custom color matching works as a defined workflow:

• Reference artwork — you provide the reference artwork or color standard you need to match.
• Sample production — matched-color samples are produced in 15–20 days, so you evaluate the actual ground pigment stick, not a printed approximation.
• Approval and production — once you approve the sample, the order runs in the standard 35–50 day production window with the same per-batch concentration and adhesion testing.

Because custom colors run through the same QC chain as the standard set, a custom shade inherits the same lightfastness discipline and batch documentation — it is not a downgraded side product.

Quality Control and Shipment Documentation

Colored ink products live or die on consistency, so the QC chain is built around measurable checks:

• Pigment concentration testing — each color batch is measured for pigment concentration before packaging.
• Adhesion testing — adhesion to the writing surface is verified per batch, addressing the market's most common field complaint about colored sticks.
• AQL inspection — finished shipments are inspected to a defined acceptance level, giving both sides a contractual basis for acceptance.
• Export QC photo reports — shipments are supported with export QC photo reports, so your team can review the goods' condition before they arrive.
• Lightfastness test reports — delivered with the goods, documenting the tested lightfastness grade that backs the product claim.

Together, these records mean a shipment arrives with its own evidence file: what the pigment concentration tested at, how adhesion performed, and what lightfastness grade was measured. For institutional buyers, that documentation often decides whether a purchase order is signed at all.

We serve painting studios, cultural institutions, and gift distributors across Southeast Asia, Japan, Korea, and the Middle East, with full OEM and ODM support. The FOB / CIF / DDP trade-term options let you match shipping responsibility to your own logistics setup.

Case: Singapore Museum Store Program, 500 Sets

A cultural gift distributor in Singapore planned a 500-set order of colored Hui ink stick sets with custom branded gift boxes for a museum store collection — a program where color accuracy and documentation would be examined by the museum, not just by the distributor.

• Sampling: color reference cards were provided within 10 days, letting the museum verify the palette before production.
• Production: the 500 sets were completed in 42 days, within the standard 35–50 day window.
• Delivery: the shipment was delivered with lightfastness test reports, closing the documentation loop the museum required.
• Result: the museum store sold out within three months and reordered for the next exhibition cycle.

The case illustrates the buying pattern this product is designed for: documentation first (reference cards and test reports), then volume. Programs that lead with verified color data are the ones that come back for reorders.

Where to Meet Us

The Colored Hui Ink Stick Set has been displayed at the China International Cultural Industries Fair and the Hong Kong Gifts and Premium Fair, where visitors examined the color reference cards firsthand and discussed custom color matching for institutional collections. Seeing the actual sticks and cards side by side is the fastest way to evaluate color quality — photographs flatten exactly the differences this product exists to control.

Before You Place an Order

To make your first inquiry efficient, have these points ready:

• Palette: the standard five-color set, or custom color matching from your reference artwork (allow 15–20 days for samples)?
• Volume: how many sets — the MOQ is 30 sets, and larger programs unlock more packaging options?
• Packaging: private-label gift box design, including your logo, language, and packaging specifications?
• Documentation: which reports does your program require — lightfastness test reports, QC photo reports, or both?
• Timeline: your target launch or exhibition date, so sampling and the 35–50 day production window can be planned backward from it.

Frequently Asked Questions

1. Can you produce custom colors beyond the standard five?

Yes. We offer custom color matching from your reference artwork, and sample production takes 15–20 days. Approved custom colors run through the same batch testing as the standard set.

2. Are the mineral pigments safe for use?

Yes. All pigments meet ASTM D4236 safety standards and are tested for heavy metal content — an important checkpoint for education channels and institutional programs.

3. Will the colors fade over time?

The pigments are formulated for stability and the lightfastness performance is tested at grade 4+ under ISO 105-B02. Test reports are delivered with the goods so the claim is documented, not just stated.

4. What is the minimum order quantity?

The MOQ is 30 sets. For custom color programs, contact us — the MOQ framework is the same, with sampling scheduled first.

5. How long does an order take?

Production runs 35–50 days from sample approval. Custom color matching adds a 15–20 day sampling stage before that window begins.

6. What documentation ships with an order?

Every shipment includes a color reference card; lightfastness test reports and export QC photo reports are delivered with the goods, giving your receiving team a complete verification file.

7. Can the gift box be customized with our brand?

Yes. We support custom gift box design with your brand logo, language, and packaging specifications — suitable for museum stores, retail chains, and corporate gift programs.
