Don't Judge a Book by Its Cover—Or Should You? The Colour Psychology Behind Book Choices
We've all heard the saying, "Don’t judge a book by its cover," so many times that it’s almost become a cliché. But let’s be honest— how often do we actually follow this advice when picking out a book? In reality, colour psychology plays a pivotal role in shaping our initial perceptions and decisions. While we might consciously tell ourselves not to judge a book by its cover, the colours used on it can subtly influence how we feel about the story inside.
While we’d like to think the story inside is what truly sells a book, it’s often the cover that catches a reader’s eye first. A book cover is the reader’s first encounter with the story, setting expectations and communicating genre and mood. Without a compelling cover, even the best-written books might struggle to reach an audience.
The truth is we do judge books by their covers—especially when we're deciding which ones to buy. Readers are influenced by cover art, whether consciously or subconsciously. A well-designed cover acts like a magnet, drawing us in and offering a sneak peek into the story within. Even though we’ve been told not to judge by appearances, research confirms that we often make our reading choices based on the visual cues a cover provides.
One of the most powerful tools in cover design is colour. Whether suggesting space or creating a sense of movement and rhythm, colour always has something to say. More importantly, it can help designers nudge the readers toward a particular feeling or reaction. Colour theory is a designer’s best friend—it explains why certain colour combinations just click and how to use those relationships to communicate meaning effectively. The ultimate goal when working with colour? Crafting combinations that look visually pleasing and elicit the right emotional response. Harmony, in this case, isn’t about following a strict set of rules—it’s about the overall balance and impact the colours create together.

Colours have an uncanny ability to evoke emotions and influence our perceptions. Specific hues or combinations can suggest particular themes or moods. When used thoughtfully, colour shapes how we feel about a book before we've even opened it. For instance, pairing cool blues and greens may create a sense of mystery, while bold reds and blacks often suggest intensity or danger. By analysing a cover’s colour palette, we can uncover subtle emotional cues that hint at the story’s tone and themes.
Colours on a book cover can also reinforce its message. Take young adult fiction, for example—over the past five years, colours like red, black, and white have dominated, symbolizing boldness and intensity. As colour expert Leatrice Eiseman puts it, "To establish an immediate message, colour combinations should contain visual cues that trigger specific responses."
The cover and the blurb work together as an invitation, coaxing us into a literary world. If the design doesn’t connect with readers, even the most powerful stories can be overlooked amidst the flood of new releases, many of which risk fading into obscurity.
While we might not always realize it in our day-to-day lives, colour plays a huge role in consumer decisions, often influencing purchases without us even noticing. The same principles apply to books: the colour of a book cover can dramatically shape a reader's initial perception of the book. Colours are key to creating that first spark of interest.
Specific colours can even increase a reader's attention and interest. Contrasting colours and unique palettes make a book stand out on the shelf, grabbing the eye and influencing purchasing decisions. However, different demographics may respond differently to colour. Younger audiences tend to be drawn to vibrant, bold colours, while adults may prefer more subdued, sophisticated tones. On top of that, colourpreferences change with trends, so designers must stay updated on the latest popular palettes to stay relevant and appealing to modern readers.
Colours set expectations for both genre and tone, subtly guiding readers toward books that align with their preferences. For example, darker hues are often used for mystery novels, while brighter, more playful colours dominate children's books. The choice of colour can also vary depending on the intended genre or audience. While some colours universally evoke similar emotions, their application is shaped by the target audience and the genre itself. Take red, for instance: it might signal urgency or danger in a thriller but convey warmth and affection in a romance novel.
Finally, there’s the psychological effect of colour on memory. Bright colours and smart contrasts make a book cover easier to remember, increasing the chances of it being recalled or recommended. This connection between colour and memory boosts not only the likelihood of recall but also the chances that a book will be discussed or recommended by readers after their first encounter.
Colours have a profound emotional impact, subtly influencing our moods, behaviours, and perceptions. At a subconscious level, they play a key role in buyer decisions, often shaping our preferences without us even realizing it. As Carl Jung once said, "Colours are the mother tongue of the subconscious." From consumer goods to book covers, colour has the power to evoke feelings, influence perceptions, and drive engagement.
While personal experiences and cultural backgrounds play a significant role in shaping how we perceive colours, certain associations have become widely recognized due to their historical, psychological, and cultural significance. These associations, however, are not universal; they vary across cultures and are often shaped by personal experiences. Each colour carries its own psychological association, which guides how we react to them. These associations are frequently leveraged in branding and design to tap into consumers' subconscious.
Let’s take a closer look at the emotional impact of specific colours and how they shape our responses.
Red: Passion, Energy, and Urgency (E.g. The Scarlet Letter by Nathaniel Hawthorne)
Red can be associated with passion, energy, or urgency, but it might also evoke warmth, aggression, or even celebration depending on the context. For some, red may signal love or danger, while for others, it could represent luck or joy. On a book cover, red might suggest high-stakes drama or intense conflict, drawing readers who may be seeking excitement or energy. Its ability to grab attention can make it a compelling choice for bold visuals.
Blue: Calm, Trust, and Professionalism (E.g. Five Feet Apart by Mikki Daughtry, Rachael Lippincott, and Tobias Laconis)
Blue is often seen as calming and trustworthy, but its effect can differ. Lighter blues may feel peaceful and serene, while darker tones might convey authority or professionalism. On a book cover, blue can evoke tranquillity or emotional depth, appealing to readers who might value reassurance, wisdom, or introspection in their stories.
Yellow: Optimism, Happiness, and Caution (E.g. She Gets the Girl by Alyson Derrick and Rachael Lippincott)
Yellow can be perceived as cheerful and optimistic, but in some contexts, it might suggest caution or even evoke anxiety when overused. On a book cover, yellow might create an energetic, uplifting atmosphere, particularly for books that aim to inspire or entertain. When paired with darker colours, it could hint at mystery or complexity.
Green: Growth, Balance, and Health (E.g. Little Women by Louisa May Alcott)
Green is often linked to growth and balance, but its meaning can vary. While lighter greens might feel refreshing, darker greens could convey stability or prosperity. For book covers, green can suggest themes of nature, harmony, or personal growth, resonating with readers who might be drawn to stories of rejuvenation or peace.
Orange: Enthusiasm, Creativity, and Fun (E.g. The Subtle Art of Not Giving a F*ck by Mark Manson)
Orange might blend the energy of red and the optimism of yellow, creating a sense of enthusiasm and creativity for some people. It can be perceived as lively and dynamic. On a book cover, orange may bring a playful, adventurous tone, drawing in readers who might prefer light-hearted or dynamic narratives.
Purple: Luxury, Creativity, and Mystery (E.g. Daydream by Hannah Grace)
Purple is sometimes linked to luxury or sophistication, but it could also evoke creativity or mystery depending on its shade. Lighter purples might suggest calmness, while deeper tones can feel powerful or enigmatic. For book covers, purple might appeal to readers seeking imaginative or mysterious tales, providing an intriguing or elegant visual cue.
Black: Sophistication, Power, and Mystery (E.g. 1984 by George Orwell)
Black is often associated with power and elegance, but it may also evoke feelings of sadness or seriousness for some people. On a book cover, black might convey intensity or intellectual depth, making it a strong choice for complex, thought-provoking narratives.
White: Purity, Simplicity, and Cleanliness
White can feel pure or minimalist to some, but it might also seem sterile or empty in certain contexts.For book covers, white may suggest clarity or simplicity, making it appealing for readers who might be drawn to introspective or minimalist themes.
Pink: Compassion, Femininity, and Playfulness (E.g. Wildfire by Hannah Grace)
Pink is often linked to compassion and warmth, but its meaning can vary. Light pinks may evoke romance or innocence, while bold pinks might feel energetic or playful. On a book cover, pink can create a sense of care or vibrancy, attracting readers who might enjoy stories of emotional connection or playful adventures.
Brown: Stability, Warmth, and Earthiness
Brown might evoke earthiness and reliability for some, though others may see it as plain or dull. On a book cover, brown could signal themes of trust, tradition, or nature, appealing to readers who might value grounded and familiar narratives.
Gray: Neutrality, Balance, and Formality
Gray is often viewed as neutral or sophisticated, though it might also feel dull to some. On a book cover, gray may provide a sense of balance or seriousness, making it suitable for books that aim to explore complex or intellectual themes.
Each of these colours influences us in unique ways, shaping our perceptions and responses—whether we realize it or not. Understanding these psychological associations can help in designing effective book covers that not only attract attention but also evoke the desired emotional connection with potential readers.
Ultimately, book covers are more than just an image or a title on a page—they are a gateway to a story, and colour is one of the most powerful tools designers have to draw readers in. By harnessing the emotional impact of colours, book designers can craft covers that not only catch the eye but also connect with the reader on a deeper, more subconscious level. After all, when the cover speaks to us, we’re more likely to open the book and dive into the adventure that lies within.
