Instead blue and yellow wires are used as the live wires pulled through a conduit. Blue wire is for the light if light is included with the fan.

Electrical Wiring Color Coding System
Blue wire light fixture. Most new led lights do not require that much power and 110v is fine. One of the black and white wires goes to the light fixture. The more lightbulbs the more wires. Green wire is for the ground. Connect the two white wires from the light fixture to the white wire located in the electrical box by twisting an orange wire nut onto. Green to green with yellow stripe.
Wire the light fixture with double wires to the power supply wires. This may give a good insight as to whether or not you can cap it off or use it and cap off the black. White wire is neutral. If you are running 220 volt or more then you will probably have multiple hot wires connecting to the fixtures brown wire and blue wire. Can you look deeper and see where the wires connect inside the fixture. It is possible this was intended for use in a ceiling fan where the fan uses the black wire and the light uses the blue wire.
Blue and yellow electrical wires while wires in these colors carry power they are not used in typical outlet wiring. Each lightbulb socket must have a separate black and white wire to supply electricity to the lightbulb. Black wire is for the fan. The blue wire is the hot wire for the ceiling fan light fixture. Most ceiling fans come pre wired with a blue wire therefore a light kit may be added as an option. The ceiling fan motor does not have a ground wire.
If you had a red wire coming from your ceiling it is hooked up to your wall switch. Wiring a light fixture or new appliance. For example you might see yellow wires as switch legs to ceiling fans structural lights and outlets paired with light switches. If you have a blue and black wire coming from your household circuit you should have two switches on your wall. Remember that you should only run higher voltage if you have to. Some home are pre wired with a separate red wire from the wall switch box to the ceiling fan box to allow from a separate switch that will control the light fixture.
Dont be confused by the number of electrical wire colors you findweve got just the guide to help you decipher their color coding. If the light can be turned on or off from switches at each. Find the short green wire or the green ground screw on your ceiling fan hanging. Let us know where it goes. The other black and white wires are the electrical circuit for the switch.
