Convert from Sto Design Architectural Colours to RAL®

Short description

If you want to transfer a color from the Sto Design Architectural Colours collection to the RAL® system for industrial or architectural use, you can convert from Sto to RAL. The Sto color is analyzed using its LAB value and compared with standardized RAL shades to find the most visually similar match.

Converting Sto to RAL is especially useful for architects, planners, and façade builders who need to coordinate Sto coatings with RAL colors — for example, on metal structures, powder coatings, or industrial components. qConv compares the LAB color data of both systems and provides the closest RAL equivalent with Delta-E value and visual preview.

Since Sto paints are usually based on mineral or polymer binders and RAL represents industrially standardized paint tones, the conversion from Sto to RAL is not exact but offers a highly precise visual match — ideal for practical planning and specification.

How does the conversion work?

In the conversion from Sto to RAL, Sto colors are first measured in the LAB color space and then compared to the LAB profiles of the RAL Classic and RAL Design systems. qConv uses the Delta-E method to determine the perceptually closest RAL shade.

For example, Sto 32101 White roughly corresponds to RAL 9010 Pure White, while Sto 37390 Granite Gray is similar to RAL 7037 Dusty Gray. qConv automatically displays this Sto-to-RAL conversion with precise LAB values and percentage deviation.

This color conversion from Sto to RAL is ideal for construction and renovation projects where materials such as plaster, paint, metal, and plastic must be color-matched. It helps prevent color mismatches early in the planning phase.

Example & application

Example: The Sto color Sto 35700 Umbra is very close to RAL 8025 Pale Brown. qConv calculates this Sto-to-RAL conversion in real time and also provides suitable alternatives — such as lighter or cooler tones depending on the material and context.

The conversion from Sto Design Architectural Colours to RAL is ideal for façades, interiors, or surface coatings combining Sto products and RAL-coated components. qConv supports you with precise LAB comparisons, Delta-E analysis, and color recommendations.

Tip: Use the Sto→RAL conversion before tendering or production approval to ensure that all trades involved use the same color reference — whether paint, plaster, or powder coating.

* Note:

qConv.com searches for the next matching color from the selected color palette. In most cases, there will be minimal or apparent color differences because there is not an exact match for every color.

Sto Design Architectural Colours

Short Description

The Sto Design Architectural Colours are an exclusive color collection by Sto, created specifically for sophisticated architectural and project designs. Developed by the StoDesign studio, this system combines aesthetic design principles with technical precision. It includes over 300 carefully selected architectural tones, perfectly tailored to modern materials, lighting conditions, and building concepts.

Unlike general color systems, the Sto Design Architectural Colours focus on the effect of color within space and on architectural surfaces. The collection unites natural, mineral, and urban nuances into harmonious palettes designed for long-lasting, architecturally refined color concepts. All shades are based on precise LAB values and are highly weather-resistant, UV-stable, and reproducible.

Usage

The Sto Design Architectural Colours are used worldwide by architects, interior designers, and color consultants. They are ideal for color design in façades, interiors, plaster and coating systems, as well as public and representative buildings. When combined with Sto coating products such as StoColor Lotusan®, StoColor Dryonic®, or StoColor Silco, they result in durable, aesthetically superior surfaces with maximum color stability.

The collection is designed to provide creative freedom and reliability: all shades are available across different materials and can be precisely converted into other systems like RAL, NCS, or Sikkens using qConv to plan and coordinate color schemes digitally.

Tips for Designers & Agencies

The Sto Design Architectural Colours are perfect for modern architectural projects where color is seen as an integral part of spatial and façade design. During planning, pay attention to lighting, surface texture, and the surrounding environment to achieve the desired color atmosphere. Neutral grey and sand tones are particularly popular as base colors for contrasting accents.

With qConv, you can analyze the Sto Design Architectural Colours online, find complementary shades, and export complete palettes. This makes it easy to develop high-quality aesthetic concepts — from digital simulation to real-world application.

RAL® Color System

Short Description

The RAL® color system is an internationally recognized standard for defining and communicating colors. Originating in Germany in 1927, RAL established a consistent catalog that assigns each color a unique four-digit number, such as “RAL 3020 Traffic Red.”

The classic RAL® palette includes 213 standardized colors in the RAL Classic collection. Each tone is precisely defined to ensure color consistency across materials, manufacturers, and applications. Beyond RAL Classic, there are also the RAL Design System Plus and RAL Effect lines, offering more than 2,500 colors for architecture, product design, and industrial coatings.

Usage

RAL® is widely used in architecture, construction, automotive, and industrial manufacturing to define exact color specifications for paints, coatings, and materials. It is the standard reference for designers, engineers, and production companies that require accurate and repeatable color matching worldwide.

Designers often use RAL colors when creating brand elements, interiors, and exterior coatings. The universal numbering system ensures that a chosen RAL color looks the same across all production environments.

Tips for Designers & Engineers

When selecting RAL colors, consider the surface finish — glossy, matte, or textured coatings can affect perception. Always compare samples under realistic lighting conditions. The RAL Design System Plus offers finer gradations for designers who need nuanced hues for product and interior applications.

With qConv, you can convert RAL® colors to HEX, RGB, CMYK, Pantone® or HKS® formats, making it easy to align digital and physical color specifications within your design process.
