Legibility
What makes a piece of visual communication legible?
For a piece of visual communication to be legible, whether it is on a billboard, magazine cover or a website, it has to be clear to read and easy to understand visually for the audience.
As you can see from the images I have show above you can straight away see which one is the legible example. Colours are an important feature in legibility. If you look at the two images above, in the list of bad contrast colour combinations, the text appears blurry and it is almost impossible to be able to read, especially from a distance this is because the colour of the text is two similar to the background it is on and has a very poor contrast. But then if you look at the other example, good contrast, simply choosing colours that have a high contrast to each other makes a big difference, its a lot more clear easy to read and has a much more legible outcome.
Tone of voice
Tone of voice
When communicating visually with an audience its important to include a tone of voice, it is one of many ways of getting the message across without causing any confusion. If the wrong tone of voice is used for something people can sometimes get mixed meanings. Tone of voice can be produced either by using image or text.
Above here are some examples i created of tone of voice used correctly and incorrectly.
You should be able to see that the writing on the left is correct; the right tone of voice has been used with each word to show how the word would sound like or feel like. But then if you look at the words on the right hand side you may notice that there is something not right, it gives mixed messages to the person reading them. This can lead to confusion to the audience. This is an example of bad tone of voice. Simple font faces and sizes can make such a difference to the outcome of a visual piece of communication when used correctly.
