Answer / madhvaraj
Red, Green and Blue are the three primary colours. These colours are unique and cannot be formed by mixing any other colours. More over they are distinctly visible for identification.As we require a 4th colour for representing neutral, the mixture of red and green, i.e. yellow is taken for representing phase and the green, universally accepted for
safety is representing earth.

in other country in place of RYB other convention is also
used

Answer / sath
The color coding in a conductor is only for identification
purpose.there is no other technical reason for that.

Answer / prosenjit majumder
I think use of colour coding for three phase system is
only for identification . you can use other colour code
also.

Answer / suni
First- for Identification Purpose
Second- RYB Electrical standard so every common pepole can
identify
third -All motor or other end side device are mention with
RYB only so they maintain the same in phase system

Answer / d4
Red, yellow and blue being the primary colors are used to
represent the three phases and usually black is used for
neutral. There is no specific technical reason.

Answer / james siruet
RYB is the most common colors used in KSA. For them to simplifies electrical wiring a they can easily determine what is hot/ live or ground..there's no other specific technical reasons.

Answer / raymond johnson
In addition to identification, the color code identifies the phase rotation. If the convention is followed from beginning to end, a three-phase motor will rotate in the correct direction.
