Interesting colour concept

I have come across many such advertisement where logo colour is used consistently in or around the subject/matter/lead actor or actress. These colour make a impact same as that of MIRANDA ad which say "Orange dekha tho dil bola Miranda". Below are the ad which we would have seen (do notice the logo colour being shown or highlighted)

Idea and abhishek turban (yellow)

Reliance and hrithik (blue and white) & background orange complimenting

Reliance and hrithik (white) and purple with hrithik shirt design colour

Vodafone and zoozoo (white and red)

Dhoni & Aircel colours (blue and red)

Airtel and shahrukh (red and white)

Airtel and football and background complimenting (red and white)
Airtel and kareena saif (red and white)
Airtel and lead girl (red and white)

Tata sky and aamir khan (blue and red)

tata sky and puppet (blue and red)

INTERESTING COLOUR CONCEPT.... isn't it?
