Green beige, oyster white, sand yellow, rape yellow and olive yellow are some of the colors you might come across when referring to RAL colors, a color matching system that is popular in the European region.
In the world of painting, its main use is for varnish and powder coating for effect and design and used mainly for color communication in:
- Road safety
The German State Commission for Delivery Terms and Quality Assurance developed the system patterned after printing’s used system, the Pantone colors. Now the Central European Color Standard uses the RAL color chart as reference to define standard in colors in the services mentioned. The system allows for wider color spectrum in which additional modification to suit preferences can be made.
The System that is RAL Colors
A collection of 40 colors called the RAL 840 was introduced when the RAL color chart was first developed in 1927. It was relabeled to RAL 840 R as tints were added. This development changed the way manufacturers referred to colors from physical exchange of samples in order to show a particular hue to simply referring to numbers based on the chart.
By the early 1960s, the system colors increased to 210 and the numbers, especially when accidentally transposed, caused some misunderstanding. The label was again revised to RAL 840-HR and the color names were modified for specific individuality.
Further System Improvement
RAL 841-GL with 193 RAL colors was introduced in the 1980s to include glossy surfaces improving the previously matte paint exclusive RAL 840-HR.
These labels known as the RAL Classic became the top choice for important color requirements in the manufacture of warning and traffic signs in different organizations and public services particularly those under the government.
Some examples of the RAL Classic use where shade is indicated by the first digit:
- Swiss Postal Service – RAL 1004
- Austrian Postal Service – RAL 1021
- German Postal Service – RAL 1032
Additional Use for the RAL Color Chart
RAL F9 was created in 1984 and is used by the German military for camouflage purposes. It has a collection of three colors namely green bronze (RAL 6031), leather (RAL 8027) and tar (RAL 9021).
Despite the RAL colors’ existing labels, a new kind of color language under the system was created. This catered to the needs of the design, advertisement and architectural industry, the RAL Design.
- It has 1625 colors (previously 1688 but was revised and reduced).
- It carries no names and no numbers patterned after the CIELAB colors.
- A 7-digit code represents the colors, the code grouped in pairs of 3 or 2 to signify tone, brightness and saturation.
- There is no interconnection between RAL Classic and RAL Design colors.
RAL Digital software allows more creative applications in colors through the incorporation of Classic, Effect and Design. It is a tool that gives more creative freedom to interior decorators and architects.
For industrial applications, there is the RAL Effect with 420 solid colors, 70 of which are metallic in nature but are free of lead, chromates and cadmium.
As further aid for designers a planning tool called RAL Color Feeling allowed more professional touch and personal creation through color combination.
Putting a Stop to Confusion
The RAL Color Chart established a common color language that helped end the confusion and mix-ups when matching or mixing colors. With 40 standard colors for a start, the system now boasts of over 1800 colors. The three numbers assigned to each systematically shows the first digit as degree of hue, the second digit for lightness and the third digit for chroma. Therefore, the color confusion ends and the common color language takes over for better rainbow connection.
