I assume you are asking about matching up the colors. The only to know for certain is to trace the wires or test them for currant.
Typically in a ceiling fan or exhaust fan the black, yellow, and blue are black=fan, blue=lighting, and yellow=neutral. Typically brown, black, and blue are all used as hot wires or switched wires. The brown or the blue could be standing in for neutral so, again, the only way to tell and be certain is to test each lead with an electrical tester.
In electronics, these colors could be anything.
Normally when you have these combinations there are special plugs at each end of each set but I assume they are missing so you may have to contact the manufacturer or call an electrician.
Hope this helps.

In electrical wiring, the live or "hot" wire is typically brown or red, the neutral wire is typically blue or black, and the ground wire is yellow or green. So, in this case, the brown wire is likely the hot wire, the blue wire is the neutral wire, and the yellow green wire is the ground wire.
Y is yellow, b is indeterminate because it could be blue, black or brown. Morr commonly you would see y/bl for yellow/blue, y/bk for yellow/black or y/br for yellow/brown.
There is not a car made by Honda called an Integra, however Acura does make an Integra. For the 1990 Acura Integra, the radio constant 12v+ wire is blue/white, the radio switched 12v+ wire is yellow/red, the ground wire is black, the illumination wire is red/black, and the antenna trigger wire is yellow/white. For the front speakers, the left front speaker wire (+) is blue/green, the left front speaker wire (-) is gray/black, the right front speaker wire (+) is red/green, and the right front speaker wire (-) is brown/black. For the rear speakers, the left rear speaker wire (+) is blue/yellow, the left rear speaker wire (-) is gray/white, the right rear speaker wire (+) is red/yellow, and the right rear speaker wire (-) is brown/white.
you cut the yellow and black wire from the origanal plug and wire these from the CD player wire the yellow, red, blue, wire into the yellow and the black from origanal plug to black on CD player
The brown wire is live (Mr Brown is a live wire!)Blue is the neutral wire for the return current. Green/yellow is the earth wire.
blue,brown,green and yellow

Green with Yellow Stripe Wire - Earth Wire (E) Blue Wire - Neutral Wire (N) Brown Wire - Live Wire (L) When you look at the plug with the terminals facing towards you: /\ / \ / E \ / \ / \ / L N \ ------------------
In a Ford Fiesta, the radio constant 12v+ wire is yellow/red, the ground wire is black/blue, and the illumination wire is blue. For the front speakers, the left front speaker wire (+) is white, the left front speaker wire (-) is white/brown, the right front speaker wire (+) is white/violet, and the right front speaker wire (-) is white/orange. For the rear speakers, the left rear speaker wire (+) is white/green, the left rear speaker wire (-) is brown/yellow, the right rear speaker wire (+) is brown/white, and the right rear speaker wire (-) is brown/blue.
Brown = live (hot) - (equivalent to Red wire) Blue = neutral - (equivalent to the Black wire) Yellow and green = earth. --------------------------------------------------------------------------- However never rely on the wire colors - you should test the wires with a meter to be sure that the person before you has not made a mistake further back in the wiring.
The wiring color codes for a 1991 Honda Civic are easy to follow. The radio constant 12V+ wire is white/blue, the radio switched ignition 12V+ wire is yellow/red, the radio ground wire is black, and the radio illumination dimmer wire is red/black. For the front speakers, the left front speaker wire (+) is blue/green, the left front speaker wire (-) is gray/black, the right front speaker wire (+) is red/green, and the right front speaker wire (-) is brown/black. For the rear speakers, the left rear speaker wire (+) is blue/yellow, the left rear speaker wire (-) is gray/white, the right rear speaker wire (+) is red/yellow, and the right rear speaker wire (-) is brown/white.
In a 2003 Kia Rio, the battery constant 12v+ wire is yellow/blue, the accessory switched 12v+ wire is brown/red, the ground wire is black, and the illumination wire is blue/black. For the front speakers, the left front speaker wire (+) is white/red, the left front speaker wire (-) is white/green, the right front speaker wire (+) is yellow/red, and the right front speaker wire (-) is yellow/blue. For the rear speakers, the left rear speaker wire (+) is red/green, the left rear speaker wire (-) is red/black, the right rear speaker wire (+) is green/red, and the right rear speaker wire (-) is green/yellow.
