Every shop needs a theme for their target audience and marketing is used to attract them to view your shop or product.
However many have neglect the primary colour of the theme. This is extremely important as it will influence the decision making process of the consumer after marketing such as advertisement is done.
Once you set a primary color for your brand, use it constantly.
For my online shop I used pink color as my primary color and therefore whenever people recalls of my shop, first think came into their mind will be the pinkish website that is cater for couple.
McDonald’s uses yellow and red as their primary color therefore the logo, product and banner are closely related to red.
On top of that, you may add related color to bring out the feel and create intention to purchase.
For Mac website, they use orange, green and white to bring out the freshness of the product. After you view their website, do you feel hungry?
This is the power of branding, it creates a vision for your future path.
