Below is a diagram of a typical power transformer. This one has a primary winding, three center-tapped filament windings, and a center.
Common Power Transformer Color Code SchemesNon-tapped Primary Leads: Black & White. Transformer Lead Color Code A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors - the transformer's coils or "windings". Except for air-core transformers, the conductors are commonly wound around a single iron-rich core, or around separate but magnetically.
Let's say I have a transformer with 3 coils. When primary coil is connected to 230V, two secondaries output 12V. Wires are color coded, but I don't know what colors stand for and there is no information about that on manufacturer's website.
Is there any relatively easy way to determine which wire is primary, which is secondary and which is start to the secondary and which is end of the. The standards committee of the RTMA (Radio Television Manufacturers Association), and previously the RMA (Radio Manufacturers Association), adopted a standard color code for components. This code enables easy visual identification.

Does not make a difference of color coding so long as you maintain color coding for the two different nominal voltage IE 120/208 and 277/480 NEC 210.5. Although I would say that typically A-Black-X1, B-Red-X2, and C-Blue-X3 is the standard for 120/208. Color Information: Transformer Color #a5acb7 The Hex color #a5acb7 is defined as light, and the closest Websafe version is #999999.
A complement of this color would be #b7b0a5, perceived brightness of this color 171/255 and the grayscale version is #ABABAB In a RGB color space, hex is composed of 64.7% red, 67.5% green and 71.8% blue.
