Is the basic identification color for industrial pipes the color of the paint applied to them?

The basic identification colors, identification symbols, and safety markings for industrial pipelines (GB7231-2003): do the basic identification colors refer to the color of the paint applied to the pipelines?
For insulated pipelines, it is actually the color of the insulation protective layer’s color ring.
The color of the pipeline is determined by the fluid flowing through it and related parameters; as shown in the figure above, care must be taken to this regard.
It can be the color of the paint applied to the entire length of the pipeline, or it can be done in any other manner specified in the standards.
For those without insulation, the topcoat is applied uniformly; for those with insulation, it is applied in sections as specified, with markings applied at the junction points. The same applies to stainless steel pipelines as well
