The best poster color depends on your goal, but high contrast (light background/dark text or vice versa) is crucial for readability, with white/light backgrounds (for space) and bold colors like red, yellow, blue, or green (for attention) being top choices, using a palette of 3-5 colors for cohesion, and focusing on clarity over busy designs to ensure your message stands out.
I would advise bright white, off-white, cream, pale grey, or possibly black as colours for poster paper. You want high-contrast but nothing that is too busy or bright. You don't want the background to compete with text or images. Simple is Best. Less is More. A Clean Look is Professional.
Use red to highlight important information, calls to action, or to draw attention to specific areas of your print materials. Yellow is one of the most visible colors from a distance, making it perfect for grabbing attention. In fact, the human eye is more likely to be drawn to yellow than bold hues like red or blue.
The 3 color rule is simple: pick one primary color. Then, pick two other complementary colors. See the example below. We picked a main hue (a variation red), and complemented it with two different colors.
In addition, red has been shown to increase the heart rate and stimulate the brain, making it a powerful aid in attracting attention. Blue is another notable color for catching the eye.
In Chinese culture, the luckiest colors are red, yellow and green. The unluckiest colors in China are white and black. There are also neutral colors that depend on context, such as grey and blue.
In the present study, using a dot-probe task coupled with EEG recording, we demonstrated that the color red captures attention and facilitates congruent motor response, particularly in an emotional context.
The 7 colours of rainbow are always observed in the same order due to how light bends and spreads. These are Red, Orange, Yellow, Green, Blue, Indigo, and Violet. They form the famous band known as the visible spectrum. To remember the 7 colours of the rainbow in order, use the acronym VIBGYOR or the phrase ROY G. BIV.
Great 3-color combinations often follow color theory (like triadic palettes - e.g., Red, Yellow, Blue) or create specific moods, such as Teal, Magenta, Gold for vibrancy, Sage, Pine, Cream for calm nature, or Red, Black, White for bold contrast. The key is balance: use one dominant color and the others as accents for harmony.
The 80/20 color rule is a design guideline suggesting 80% of a space uses a dominant color or palette, while 20% uses an accent color or contrasting palette for balance, creating depth and visual appeal. This helps achieve a cohesive, designer look, whether it's applying warm (80%) and cool (20%) tones, or 80% neutrals with 20% bold accents like bedding or decor.
Red and orange seem to be the clear winner when it comes to eye-catching colors. These colors tend to stand out and are therefore used on many warning signs or safety equipment. Yellow is another color that comes in a close second to red and orange in popularity.
Incorporating Eye-Catching Graphics and Images
Graphics and images play a crucial role in making a poster more attractive and engaging. The right visuals can enhance the message, draw attention, and evoke emotions, making your poster stand out in any environment.
The 3-Color Rule in fashion suggests limiting an outfit to three main colors for a balanced, cohesive look, typically a dominant color, a secondary color, and an accent color, with neutrals like black/white often acting as a base or exception but still counting towards the limit. It's a guideline, not a strict law, helping to avoid overly busy or clashing combinations and making mixing patterns and accessories easier by focusing on color palettes, using patterns as single colors, and incorporating pops of interest.
Here are some of our favorite two-color combinations.
Poster colors, also known as tempera paints, are water-based paints that offer excellent opacity and coverage. They have a smooth and creamy consistency, making them easy to work with on various surfaces such as paper, cardboard, canvas, and more.
The cool neutrals create a sense of calmness and tranquility, while the varying shades of green, blue, and purple are refreshing and promote a peaceful state of mind. These vibrant colors perfectly resonate with Gen Z's modern aesthetic and their affinity for digital and fashion influences.

The rainbow emoji is commonly used as a symbol of the LGBTQ+ community. Some people might add a 🌈 into their social media bio to self-identify as queer. Alternatively, you can use the rainbow emoji to express pride and support for the queer community or parts of queer culture.

Blue is renowned for its calming properties. It's often used to reduce stress and anxiety, create a sense of tranquility, and aid in sleep. Blue light therapy is often used to treat Seasonal Affective Disorder (SAD), and lighter shades of blue can be beneficial in bedrooms.
For example, Buscemi has found that blues, greens and muted brown tones tend to be great choices for both adults and children with ADD and ADHD.
