Welcome to the Silk Plaster colour catalogue - a searchable reference of more than 54,000 paint and coating shades from the world's leading colour systems, all in one place. Whether you are matching an existing wall, specifying a project or looking for the closest equivalent in another brand, this guide explains how the catalogue works and how to move between colour systems.

What is the colour catalogue?

Every colour in the catalogue has its own page with the exact HEX code, an RGB breakdown and a live swatch, so you can see the shade on screen. Each colour also lists its closest visual matches from other brands and fan decks, ranked by colour accuracy. This turns the catalogue into a practical cross-reference tool: start from any shade and instantly find the nearest equivalents elsewhere.

Colour systems and fan decks we cover

The catalogue brings together the major architectural and decorative colour systems, including:

Alongside these you will find Benjamin Moore, Sherwin-Williams, Caparol, Farrow and Ball, Little Greene, Tollens, Valspar, PPG and many more.

How to convert between colour systems

Colour systems such as RAL, NCS, Dulux, Sikkens, Pantone and Tikkurila each use their own naming and numbering, but a colour is ultimately defined by how it looks. To convert a shade, open its catalogue page and read the closest matches section: it lists the nearest colours from other systems, each labelled with its source palette and an accuracy value. For example, from a Sikkens shade you can find the nearest RAL code, or from a RAL colour the closest Dulux or NCS equivalent.

How to read a colour page

On every colour page you will find: the colour name and code, the HEX value (for example #CBBC8A), the RGB values, a large swatch, and the closest cross-brand matches with links. Use the swatch and HEX for digital work, and the cross-references to source or specify the same shade in a different product range.
