These particular signs are extremely legible due to the fact that they are used for emergency's. They are both created using bright colours to catch peoples attention and they use the rule of putting the contrast of the writing in white to the colour surrounding it so that the words stand out more.
This sign is legible as it is used for the purpose of advertising. Rolex the watch manufacturer have their crown symbol and green capital letters as their company face, so wherever people are they can recognise this is the Rolex brand. the sign stands out as it is lit up, big letters and contrasting colours of bright luminous green and a black outline make the words jump out at the audience.
This map to me is extremely illegible as, firstly the writing is small and black and the colours used to show the routes are quite similar such as the pastel green and blue. The maps writing needs to get bigger and bolder using more visual colour to enhance it.
