Fat is found in whole milk – milk is mainly small droplets of animal fat dispersed in water. The washing up liquid wants to do the same thing, break the fat down in the milk. We call it an emulsifier as it allows the water and fat to mix creating an emulsion. The emulsifier molecules have a water loving head and a water hating tail. The tail sticks into the fat droplet and surrounds it leaving only the water loving heads. While it is doing that it scatters all the colour creating the display you see above.
