Appiani · Design Journal · Bespoke ceramic mosaic
A laying pattern can become a project's signature. With Pastelli Custom, Appiani explores the expressive potential of ceramic mosaic through modular geometries, nuanced colour combinations and layouts conceived for architects and interior designers.
01 / The surface as a language
Ceramic mosaic beyond a mere covering.
In architecture, a laying pattern is not simply an installation detail. The arrangement of individual tesserae, the repetition of a module and the relationship between colour and joints all change the way a surface is perceived. Geometry can introduce rhythm, reinforce spatial identity or create a quiet, continuous backdrop.
This is the premise behind Pastelli Custom, the full-body porcelain stoneware collection by Appiani: a flexible system through which designers can develop an expressive and coherent surface. Its range comprises 12 custom laying patterns, from A to L. Existing patterns can be reinterpreted in different colours, while new layouts using available sizes can be studied subject to technical feasibility.
02 / New layouts
Four additional Custom patterns: I, J, K and L.
The four patterns extend the collection's geometric vocabulary. Each composition is shown with an example colour combination in the catalogue. These colours are a point of departure, not a fixed specification; designers may explore new chromatic solutions with the Appiani team.
Custom Pattern I
Aurora, Conchiglia and Nocciola create a warm hexagonal pattern with a distinctive rhythm.
Catalogue colour example: Aurora · Conchiglia · Nocciola.
Custom Pattern J
Conchiglia, Osso and Nocciola form a modular composition with carefully balanced contrasts.
Catalogue colour example: Conchiglia · Osso · Nocciola.
Custom Pattern K
Antracite, Cenere, Ostrica and Osso define a graphic, four-colour geometric pattern.
Catalogue colour example: Antracite · Cenere · Ostrica · Osso.
Custom Pattern L
Osso and Aurora create an essential two-colour layout that highlights the rhythm of the tesserae.
Catalogue colour example: Osso · Aurora.
The Pastelli 2026 catalogue specifies 2.5 × 2.8 cm hexagonal tesserae, a 60 × 60 cm pattern and a 30 × 30 cm module for layouts I–L. The illustrated examples use Kerakoll KK1 or Mapei 100 Bianco grout. Colours and combinations can be customised; the result should be checked against a physical sample.
03 / An open system
Twelve layouts. Many ways to make them your own.
Alongside the latest patterns, Custom A–H provide a rich repertoire of arrangements for floors and walls. The value of this system lies not only in the number of available designs but also in the possibility of selecting a visual rhythm appropriate to the architectural context.
The examples below introduce the broader family of Pastelli compositions. For up-to-date technical information, samples and colours, always refer to the official collection page.

04 / Colour as a design tool
One geometry, many identities.
Pastelli has a palette of 16 shades: Neve, Antracite, Cenere, Ostrica, Osso, Burro, Corda, Conchiglia, Nocciola, Miele, Salvia, Ruscello, Muschio, Ottanio, Oceano and Aurora. Close shades produce understated, continuous surfaces; stronger contrasts accentuate the pattern and make its modular structure visible.
Grout colour also influences the final result. Tone-on-tone joints can soften a composition, while contrasting joints highlight its geometric rhythm. Always evaluate the combined effect on a physical sample under the relevant lighting conditions.
05 / From drawing to production
Custom Layout: bringing a pattern into the project.
There are two complementary ways to personalise Pastelli. The first starts from an existing layout and adapts its colour combination. The second begins with an original geometric concept, developed using available tesserae and formats. After feasibility checks, the appropriate template may be produced using 3D printing.
The assessment considers visual intention and practical requirements alike: dimensions, installation, intended use, quantities, production parameters and sampling. This is how Custom Layout becomes a dialogue between design vision and ceramic production.
Catalogue colour examples are illustrative; combinations and any new geometric layouts require technical verification. Colour perception varies with lighting, grout and production lots.
06 / For design professionals
How to start a bespoke mosaic project.
A clear brief should describe the intended application, approximate area, preferred colours, relevant drawings or references, the design stage and the expected schedule. This information helps Appiani assess which customisation route is appropriate and whether a sample or prototype is needed.
Pastelli can be considered for residential, hospitality, retail and contract projects, provided the specific technical requirements are checked for each application.
07 / Frequently asked questions
Designing with Pastelli Custom.
Can I change the colours of Pastelli Custom patterns?
Yes. Catalogue layouts are references. Alternative combinations using Pastelli colours can be evaluated according to the selected scheme.
Can I request an original laying pattern?
Yes. Architects may propose a layout developed from available tesserae and formats. Appiani checks feasibility and can develop a 3D-printed template where appropriate.
What are the new Pastelli Custom patterns?
The repertoire comprises 12 patterns A–L, including the additional I, J, K and L compositions.
Does grout affect the final design?
Yes. Grout colour and joint dimensions affect how the geometry is perceived. A physical sample is recommended.
How do I request a bespoke mosaic?
Use the Custom Projects contact form and provide the drawing, colours, approximate quantity and intended use.
