What Colours Mean For your Readers?

All of the colours have different psychological connotations and will affect people in various ways. Colours have meanings for people which have been evolutionarily and socially enforced. These colours have just as much influence on the internet as they do in real life.

For example the most powerful psychological colour is probably Red.

Red has connotations of blood, violence, passion, love, stimulation, anger and aggression and you can use this to encourage people to take action on your blog. If you think about it all of these emotional responses require you to take action like anger requires you to either fight or to take flight both of which are very definite actions. So you should use red on areas where you want your visitors to do something, places like the sign up box ‘enter your email’ or perhaps near your Facebook like button have a red arrow pointing to it.

Suggested Niche for Red Colour Scheme – Relationship advice or dating website.

Blue –

In general blue tends to have connotations of calm, trust, coolness and intelligence. All of these things are character traits that you would probably want to have as well as emotions and so a great place to use this as a colour scheme would be your about page. Putting people at ease and projecting an image of intelligence and trust is usually what you are trying to do with the words in an about page so why not use colour to emphasise these features.

The effects of yellow are things like confidence, optimism, friendliness and extraversion. That would mean that this colour scheme would go well with a health and well-being blog or perhaps even a fitness blog. Anything where you are trying to encourage these traits from your readers. Also if you have any quizzes or questionnaires that you would like readers to complete, using yellow to instil confidence could help them to complete it.

When you see white you will often think of things like cleanliness, purity, efficiency and clarity. This is the colour that you will want to use to focus a reader’s attention on your content area. Not only do readers expect words to be written on a white background but it is also a clean area where the focus is on the words and nothing else. It can also give the impression of added space and you might know from people painting the walls white in houses to create the illusion of space. This can also work on your blog showing that the content is taking priority on your page.

White is also good on pages of your site where you are simply trying to get information across to your readers as directly and efficiently as possible so things like the contact page will really benefit from the white background.

Suggested Niche for White Colour Scheme – Company, e-commerce and profile websites.

How can we leverage or use it as a tool to market our brand. For that, let’s first understand the basics of color.

The Concept of  Colors in web conversion:

Color is broadly divided into three categories: Primary, Secondary, and Tertiary. Primary colors are red, blue and yellow.

These can be mixed to create secondary colors that are purple, green, orange. Lastly, there are tertiary colors that are combinations of primary and secondary colors.

There are six tertiary colors; red-orange, yellow-orange, yellow-green, blue-green, blue-violet, and red-violet.

For example, tertiary color produced when mixing the primary color blue with the secondary color green is called ‘blue-green.

You can create different tint (add white), shades (add black) and tones (add White + Black) using the above colors.

Thus, on the right-hand side, you can find red, orange and yellow which are warm colors and on the left-hand side are the cool colors: blue, green, purple.

Different Cultures drives different color emotions

A single color can have different meanings across different cultures. White may not be a wedding color in India.

It is a color of mourning. However, in western cultures, it is a color of celebration and wedding. Similarly, red which is associated with romance, excitement, thrill is a color of death in certain parts of Africa.

According to a study by N.Yoshioka, Blue is the color of calm across all cultures. With all that said, there are some general rules for applying color universally.

In a study published in the Journal of Experimental Psychology: General, Patricia Valdez, and ULCA’s Albert Mehrabian found that Blue, blue-green, green, purple blue, red purple and purple were perceived as the most pleasant colors while green yellow and yellow as the least pleasant. The relations were “highly consistent”, and the relationship between colors and their emotional reactions were “highly predictable”.

Color influences Men and Women Differently

Depending upon the gender your website is targeting, research has shown that women choose softer colors over brighter color while men choose otherwise.

According to a study by Hallock, Blue is favored by both Men (57%) and Women(35%) than rest of the colors. Here is the detailed analysis of the same:

What’s most notable above is both men and women dislike Orange and Yellow. However, women prefer yellow over orange while men prefer orange over yellow.

According to Kissmetrics, Men prefer achromatic colors like shades of gray or pure colors while women preferred tints.

Given how the taste of men and women is different, you should choose the color carefully by understanding that gender makes the greater percentage of your target audience or customer.

If your audience is men, try using green or shades of green.

Color Impacts Emotions and Behaviors

Color can make us feel happy or sad. It can make us feel hungry or relaxed. As a brand, it’s crucial for you know the psychological effect color has on an individual or your Client.

Let’s take a closer look on how color drives emotions and behaviors.

According to the chart above by CoSchedule, Orange portrays energy yet is inviting and friendly. It is balanced color. Similarly, yellow is associated with happiness, sunshine and hope.

It can make your design user-friendly by making the reader feel more cheerful and optimistic. This explains why yellow and orange against the white or gray backgrounds are the most used website buttons and gets maximum clicks in a majority of websites.

Remember, product page where you find the yellow “Add to Cart” and Orange “Buy Now with 1-Click” buttons.

Note: Orange and Yellow buttons should be on contrast background; if it would have been on any other background say red, it will create the same result. This is because color contrast is how our brain finds and attend to relevant stimuli.

How Color Contrast Increases the Conversion?

To check how color contrast works, let’s look at epostakur Home Page at different sizes.

Did you notice that the gray Call-to-Action button still stands out?

This is the effect of contrast, makes the most significant actions pop out increasing the conversion rates.

Studies suggest that people make a subconscious judgment about a product within 90 seconds of initial viewing. Up to 90% of that assessment is based on color alone.

I think now you know, what you need to do if you want to capture the attention of your customers by utilizing colors.

If you want people to notice you at the bar, wear bright colors which contrast with the dark background of bars. If you want to people to buy your stuff, choose a color that is opposite of your website’s background.

There are different online tools to measure color contrasts. WebAIM is a color contrast checker tool for checking the ratios of two different colors and whether they are according to Web content accessibility guidelines.

You can also use the following formula suggested by the World Wide Web Consortium (W3C) to determine the difference between two colors.

(maximum (Red value 1, Red value 2) - minimum (Red value 1, Red value 2)) + (maximum (Green value 1, Green value 2) - minimum (Green value 1, Green value 2)) + (maximum (Blue value 1, Blue value 2) - minimum (Blue value 1, Blue value 2)) The difference between the background color and the foreground color should be greater than 500.

Case Studies which shows how color affects conversions

1. CareLogger: A health app that allows you to keep track of your diabetes. They had a green Call to Action (CTA) button that they wanted to test with a new red one. After 600 signups with the exact same CTA and just a different button color, the red button saw 34% more conversions than the green.

Similarly, Unbounce changed a dark blue “Add to Cart” button on a gray background to bright green. It improved its conversions by 35.81%.

2.  UK Airline BMI – It had an urgent CTA that read “Hurry! Only XX seats left.” When they added a red background to the CTA, they increased their conversions 2.5%. Thus, Colors that coordinate with the message may increase conversions. Consistency among text and colors can help reinforce the message you want to instill in visitors.

3. Performable: Performable wanted to learn how changing the call-to-action button color would affect the site’s overall conversions. Changing the CTA button color from green to red Performable was able to increase its click-through rate by 21%

4.  Heinz: Heinz changed their signature ketchup color from red to green. Result: More than 10 million bottles were sold in the first seven months following its introduction,$23 million in sales [the highest sales increase in the brand’s history]. All because of a simple color change.


There is no sure shot solution or one right color that will work across all platforms. So, the question is how do you pick the right color? Here is my suggestion:

  1. Study the market you want to attract based on age, gender, culture and the color language they will respond best to.
  2. Do thoughtful A/B testing to determine which color combinations and positions will work best for you to generate maximum leads and conversions.
  3. Apply it on your website and keep reinventing and experimenting with colors and color contrast, brightness and saturation.

So, which Color attracts you the most. Have you done any interesting A/B testing on your website or product?
