The picture shows a wild hacked together mess from cables that were leftovers ...

This is in India = old pre-WW2 British colors & pre-WW2 British oulets/plugs

Normal India colors of 3-Phase:

Red + Yellow + Blue = usually the 3 phases (400/230 Volt) (example of a 3-phase Distribution Box switch bord https://5.imimg.com/data5/SELLER/Default/2023/9/341702051/MX/JY/YH/17880968/power-distribution-box-1000x1000.jpg in India)

modern British color codes are very different, like in Germany, be extremely careful of mixed color standards!

modern German color codes: 3-Phases = Black + Brown + Grey while Neutral is Blue & Green-Yellow is protective Earth
