How Many Colours Should a Bead Pattern Have?

When you turn a picture into a pattern, the colour choice is where the artist’s decisions happen. Every extra colour gives a closer match to the photo, but also another pack to buy, another pile to sort, and more chances of placing a wrong bead. A good pattern uses the smallest palette that still looks like the picture.

A rough guide to colour counts

These are starting points. Lower the maximum number of colours until something important disappears — an eye, a highlight, a logo letter — then go back up by two or three.

Why fewer colours often looks better

• The eye merges small differences. At bead size, two similar shades next to each other look like noise, not detail. Merging them gives cleaner shapes.
• Contrast carries the picture. Dark outlines, bright highlights and clear light/dark regions matter more than subtle midtones.
• You build faster and make fewer mistakes. A palette of ten distinct colours is easy to check at a glance; twenty-five similar greys are not.

Adaptive or fixed palette?

An adaptive palette starts from your picture. The generator finds the dominant colours with k-means clustering and names each after the nearest colour in a generic set, so the result looks like the picture with few colours. A fixed palette, such as Basic 16 or the 48-colour set, uses colours that exist in a typical bead assortment; the generator keeps the colours that represent your picture best until the maximum is reached. If you own a specific set, choose “My own list of colours” and enter its hex codes so the pattern uses only colours you can really build with.

Dithering

Dithering places two colours in a fine pattern so the eye blends them into a shade in between. It is the only way to imitate a gradient with a small palette, and it works well for skies, skin and shadows. It also adds scattered single beads, which are slow to place and easy to get wrong. Use light dithering for photographs and none for logos, text and cartoons.

Matching on-screen colours to real beads

1. Start from the legend. Each colour has a name, a hex code and a bead count in the PNG, the CSV and the colour list.
2. Compare with your beads in daylight. Screens glow and beads reflect, and phone screens are often brighter and more saturated than the real material. Hold a bead up to the screen to compare, then judge by eye in natural light.
3. Choose the nearest bead you own rather than ordering a new colour for every shade. If the nearest bead is clearly different, use Edit by hand to swap it or merge it with a neighbouring colour.
4. Check light and dark. Make sure light colours stay lighter than dark colours after you swap them. A pattern survives a small hue shift but not a reversed contrast.

How big is “close”? Colour scientists measure the distance between colours as ΔE. A value below about 2 is hard to see, values around 5 are visible side by side, and values around 10 or more look like different colours. The tools here use the CIEDE2000 formula, which is designed to match what people see, to choose the nearest colour.

Special beads

Translucent, glow-in-the-dark, metallic and pearl beads behave differently from solid colours. A translucent bead looks darker against a dark board and lighter against paper; glow beads look pale in daylight. Treat them as extra accent colours rather than substitutes for solid ones, and test a few before committing to a large piece.
