Do you judge a book by its cover? What about its color?

Have you ever wondered why most business books use dominant blue or orange colors? And why is there often a pink or red element somewhere around when it comes to romance books?

What does color theory have to do with professional book cover design?

Please keep reading to learn more about color theory in book cover design and how to use it to promote your book effectively.

The importance of color in book cover design

Why do you think the book cover for It by Stephen King includes black and red? Because the combination of these two colors hints at danger, fear, and evil. Or why a famous children’s book, Alice’s Adventures in Wonderland by Lewis Carroll, is usually published with blue, yellow, or pink covers? These hues are associated with curiosity, friendship, and happiness.   

The color isn’t something you can think about later. It’s an essential element that you should choose consciously. We will study color theory in detail to help your book cover become a powerful marketing tool.

But how do the book cover colors communicate with the audience? Before potential readers even open a book, the colors on a book cover give them their first impression. And we all know that one matters a lot.

Pro tip: When choosing a color palette for your book cover, do proper research. Concentrate on colors that create the emotional response you are looking for in your audience.

Enough theory. Now, let’s take a closer look at its majesty—color psychology.

Сolor psychology in book cover design

The idea is simple: every color represents and evokes a certain feeling. Therefore, color is a powerful communication tool that influences psychological reactions.

So, how exactly does this work in book cover design? Let’s take a look.

Red

Red is about an active lifestyle, energy, confidence, and enthusiasm. It immediately attracts attention, sometimes signifying danger (think about all the warning signs). As a result, the color red increases heart rate and boosts energy levels. However, dark red is associated with anger, rage, and prestige, as well as passion and dominance.

Orange

Orange characterizes the maturity of personality. It is the color of joy, pleasure, the pursuit of achievement (Does it ring a bell? Think about all the self-made success books!), and self-affirmation, the color of energy and strength. It has a beneficial effect on human psychology, relieving tension in conflicts.

On the other hand, it displaces different colors associated with the shock effect. In this case, the orange symbolizes the passion of the struggle and the demonic beginning of the war.

Yellow

Yellow stimulates brain activity and imagination. Pale yellow is the color of a good mood; it eliminates apathy and anxiety. Bold yellow provokes ambition, motivation, and creativity. In addition, it influences the left side of the human brain, which is responsible for logic.

Green

Light green is associated with nature, vitality, the environment, and health. However, bright green is associated with magic, mysterious light, and paranormal phenomena (as seen on Harry Potter and The Hobbit book covers).

Blue

Blue stimulates longing for travel, miracles, and magic. It is a color of peace, relaxation, and meditation. Blue calms, balances, reduces pain, and provides a sense of relief. When the reader detects blue on the cover, they may expect mental tension and involvement. The book might give them a lot to think about.

Purple

Light purple is about sensuality and spirituality. It enhances self-esteem and gives a pleasant feeling. At the same time, one of the most mysterious colors, no doubt, is dark purple. It is associated with abnormal activities, fantasy, and magic.

Gray

Gray conveys sophistication, knowledge, prestige, and wisdom. Think about images of architecture, strong urban and industrial vibes.

Pink

Pink brings youth, playfulness, emotion, innocence, dreams, and desires. It is considered to be a classic feminine color. However, different shades of pink can seem weak, vulnerable, and a bit silly. It can be associated with the refusal to face real-life challenges (remember the “rose-colored glasses” proverb?).

White

White is clean, straightforward, self-sufficient, and simple. It correlates with spirituality, energizes, and purifies. However, the white color can get the opposite value. By its nature, it seems to absorb and neutralize all other colors and correlate with emptiness, icy silence, and, ultimately, death.

Black

Black evokes a sense of authority, power, and sophistication. Dark cocktail dress, black suit, and tinted car windows. And of course, black is also associated with the dark side and depression.

How to choose a color for your book genre

Now let’s learn what colors people typically associate with specific genres. Here, we will combine the knowledge of color psychology and cover design in different genres.

When choosing a color palette, take into account the following details:

• Color psychology
• The individual’s assessment of the harmony in colors based on a specific object (e.g., green makes sense as the color of grass, but not human skin)
• Do not use more than three dominant colors on the book cover.

Non-fiction: blue, yellow (or golden), orange, and sometimes red

For non-fiction book covers, designers prefer to use yellow, orange, blue, and red because of the meanings they convey and the feelings they evoke. If you are a proud author of self-help motivational books, success stories, or thought-provoking non-fiction, this is the palette you might be looking for.

By the way

Don’t be afraid to use white space on non-fiction book covers. It has proven to make a book cover more scannable and prioritize the focus element for the audience.

Now, let’s look at the most common colors for fiction book cover design.

Science fiction: Blue, Black, Green, Red, and Gray

Many sci-fi books are set in dystopian societies, during hard times, or amid rebellions. Cool blues, purples, and metallic grays will leave the audience feeling tense and unsettled.

There’s an exciting theory of impossible fictional colors, which are the ones that do not occur in nature under normal circumstances. Some sci-fi books use these colors on their covers.

Romance: Pink, Purple, Red, White, Blue

Let’s go by the common stereotype and assume women are the target audience for romance books. As a result, it is good to use a feminine color palette for book covers in this genre.

If your book falls into the category of historical, contemporary, erotic, or paranormal romance, you might want to go with pink, purple, red, white, and blue combinations.

Fantasy: Bright Green, Purple, and Yellow

What about fantasy book cover design? Since this genre quite often involves paranormal activity, the combination of green, purple, and yellow will highlight the book’s mood. It is also a great trick to draw attention. An excellent way to represent different aspects of the unreal worlds, mystic creatures, and scenes.

Thriller: Red, Black, and Blue

If you are working on a psychological, action, crime, or mystery thriller, you might consider using red, blue, and black in your cover design.

Think about blood, aggression, fear, and power. The combination of red and black communicates that the book is about violence and mystery.
