Advertising conventions

1) colour scheme- blue white and brown, the white helps to symbolise the creaminess, the brown is to show how chocolately it is and the blue is a signature colour that shows somewhat sophistication  and fun.
    central image- this is a picture the actual chocolate in front of a stream of chocolate
    slogan- "Have you tasted smooth and creamy lately?"
    Logo- in the centre of the image is the Cadbury Dairy Milk logo

2)  slogan- This appeals to the audience as it is directly asking them if they would like something delicious in a round about way
     colour scheme- makes it look tasty and fun at the same time
     central image- it looks appealing and Delicious
     logo- as it is well known it gives a sense of familiarity

3) The USP is "Have you tasted smooth and creamy lately?" i know this because it is the only writing but also because it is a quite persuasive way to tell someone to buy a product.
