This logo is effective because the M is bold and three-dimensional and the TV looks like graffiti sprayed on to the M, giving a ‘street cred’ look which appeals to young people.
The use of bold, cheerful primary colours makes this logo instantly recognisable and distinctive. There is also something about the mainly rounded form of the letters which attracts the eye.
This logo uses only two colours – black and red. This is effective because the red heart stands out in contrast to the black text, and the two colours complement one another. It also impresses by conveying a complete sentence in four characters.
