A suite of Idents are a slideshow of Idents that are all related to each other in one way or another. One example of suites would be channel 4. Channel 4 uses the same Idents which are catered to particular times when they have the 4 forming into shape this will be in a particular time of day like morning mid day or night time and these Idents take different aspects of the world at different times like mid day they would show urban surroundings or a farm this can demonstrate hard work. When the night time ident comes on in the evening this demonstrates night life and a fun atmosphere which people can relate to this is why having a suite of idents is so important and not only that but the channel 4 is the only channel with an Ident suite. BBC also has a suite of ident which are centred around the world.

Here is a link of all channel 4 Idents which are new and old these are all set in different locations as they are allocated to specific shows and gives viewers insight in what they are about to watch. 

This ident is designed for a historical ident look and clearly shows elements of an ancient world this ident would be used particularly when a documentary is about to come on or something historical this is why its important to have suite of idents as you are able to get across to all of your viewers and give them more of an in depth look of what they are about to see. this would also be shown in the day time maybe morning to afternoon as the ident is still set in the day time and not the night time . 

This is only of the idents and its very similar to the other channel 4 idents as they all have the same 4 which forms into shape and creates a 4.

In this ident is is set at a motel at night time this is probably related to Tv shows that would be shown at night time like reality TV programs and other programs like comedies this is represented through the lively activity of everybody in the evening. This is what Channel 4 has tried to capture in this ident this is because of the fun lifestyle they have tried to use to make there channel look more appealing and fun to watch its also quite interesting just from the colours and the look of the motel as it has an intricate design. the colour are very well balanced and work well in this ident this is because of the lights and the dark background which contrasts with the light.
