Understanding 3 Phase Wire Color Codes for Different Voltages

Question:

I am well-versed in the wire color codes for 3 phase 480VAC, including brown, orange, and yellow. However, I am unsure about the proper sequence for 3 phase 208VAC. There seems to be conflicting information available online. Can anyone clarify this for me? Thank you!

When it comes to wiring, opinions may vary among experts. According to both a Journeyman Industrial Electrician and my Master Electrician instructor, the standard color coding for electrical wires is typically black, red, and blue. Based on their guidance, I will be following this color scheme for my electrical work.
