DMC Colours - Why Diamond Painting Looks the Way It Does

SECTION 1 - Observation

When converting photographs into diamond painting patterns, detail is not lost all at once, it disappears in a very specific order.

The first thing to vanish is atmosphere.

Soft lighting, glow, haze, and colour transitions flatten into visible steps.

Yet major shapes remain clear.

Two patterns can use the same resolution and still look vastly different depending on the colour system used.

This is why some diamond paintings appear vibrant and smooth, while others look speckled or posterised, even when both are technically “high detail”.

SECTION 2 - Mechanism

Diamond painting uses the DMC colour system, a fixed palette of approximately 447 colours.

This palette was never designed to perfectly reproduce photographs. It was designed to solve a manufacturing problem.

Every drill must be mass-produced, restocked, and matched worldwide. To achieve this, colours must be limited and standardised.

So when an image containing millions of colours is converted, the software must repeatedly reuse the closest available match.

That creates three unavoidable behaviours:

• Gradients compress into steps
• Glow and lighting weaken first
• Fine colour separation merges into noise

This is not an error, it is the expected outcome of mapping infinite colour into a finite system.

SECTION 3 - Studio Method

For many years, the only solution available to designers was placement strategy, deciding where to sacrifice colour accuracy so the image still reads correctly.

But after producing and testing patterns, we observed something consistent:

The limitation was not resolution.
The limitation was missing transition colours.

There were gaps between DMC shades large enough that the eye could detect the jump.

So instead of only optimising placement, we expanded the palette itself.

We developed an extended studio palette, intermediate colours engineered specifically to bridge those gaps while remaining visually compatible with standard DMC drills.

This allows gradients to step gradually instead of abruptly.

SECTION 4 - Mechanism

When those transition colours exist, the behaviour of the artwork changes immediately.

Lighting begins to blend instead of band
Water and sky regain depth
Skin tones stabilise
Glow effects become possible without noise

The image stops looking “converted” and starts looking illustrated.

The structure was always present, the palette simply couldn’t express it.

SECTION 5 - Practical Takeaway

Standard DMC ensures compatibility across all manufacturers
Limited palettes prioritise production efficiency over visual continuity
Detail loss occurs in colour transitions before shape clarity
Adding resolution cannot replace missing colours
Adding transition colours restores perceived detail

STUDIO NOTE - CONTEXT & LIMITATIONS

The DMC palette remains the foundation of diamond painting and is essential for universal replacement and availability.

Our extended palette does not replace DMC, it supplements it.

It fills the visual gaps between existing colours so artwork can retain depth while remaining fully compatible with the standard system.
