Branding.

Coldplay's album covers show  no sign of anchorage or continuity, varying significantly between the different albums, showing little/no resemblance to one another.

A Head Full Of Dreams (2015) 

Mylo Xyloto (2011)

Ghost Stories (2014)

Parachutes (2000)

One similarity is that on the majority of their covers, there is no reference to the album name, or indeed the band. This suggests how iconic they are as a band that their fans can identify an album of theirs by subtle identifiers linking it to the band. Their early work (Parachutes - released in 2000) does feature this content, which was before they became as popular as they are now, suggesting how, now they have a huge fanbase, they don't need to be as plain and obvious about their branding as to including their names on the front.

 Regularly during performances, the band like to use paint, colours and confetti. This is used by Coldplay to anchor their brand image, making their performances iconic, yet also reference between concerts and music videos.

This paint style is also used in their set design and to decorate their instruments. This further implements the iconic Coldplay brand, being unique and easily identifiable.

Each performance is made iconic through the use of the bright colours used in: lights, graphics, paint, confetti and their clothing. These are all used effectively by Coldplay to create a brand for the band which can be easily identified and is quite unique to them.
