TS 6030

TS 6030 is a standard for designating colours by letter code in electrotechnical work, providing a common notation for descriptions, drawings, markings and similar technical records. Its focus is not on how colours are perceived visually, but on how they are identified consistently in text-based technical communication.

Why coded colour designation matters

In general technical practice, coded colour names help avoid ambiguity when the same colour must be referenced across languages, drawing sets, specifications or marking instructions. In electrotechnical documentation, this supports clear communication in areas such as cable identification, legends, notes and marking schedules. A code-based system creates a shared technical language for designers, manufacturers and maintenance personnel.

What the standard covers

According to its scope, TS 6030 covers the designation of colours by letter code in descriptions, drawings, markings and similar representations used in electrotechnical fields. This means the standard addresses the way colour names are expressed, rather than the physical measurement of colour or the formulation of pigments. The document is recorded as equivalent to IEC 757:1983, placing it within an internationally recognised approach to technical colour nomenclature.

Standards of this kind are especially useful where short, stable colour references are needed instead of long verbal descriptions. Letter codes can reduce translation issues, speed up interpretation of drawings and help maintain consistency for the same colour reference across different documents.
