- Colours and font
Visual identity is very important in the net and can help your customers recognize you anywhere. For example, Coca Cola has registered their specific red colours and a bootle can be recognized anywhere in the world even before reading the name.
Another way to see the importance of colours is the action of the colours have on the subconscious.
The colours like green or blue would have more an impact as calming and processional, unlike yellow would be a colour more often associated to solar, happiness and children. If you are unsure of the colours you would like to use, start with the colours of your logo if you have one already. At the creation of your logo, you would have chosen the colours that speak to you and therefore would be the colour you are attached.
