In the world of data visualization, the visual appeal of reports can significantly impact their effectiveness. One powerful element at your disposal is color.


In this blog post we'll explore the art and science of using color in your Power BI reports to enhance clarity, emphasize important information, and even communicate brand identity. By using color thoughtfully and intentionally, we can create reports that not only convey information effectively but also look visually appealing and engaging to our audience.

I often get asked, "How do you pick the colors for your report?" or "I spend forever choosing my color palette, is it like that for you?" or "My client insists on using their company colors, but they are just so BOLD. What can I do?".


If you ever wondered about these color dilemmas, you're in the right place! We're going to tackle these questions and more in the sections ahead:




Color Theory & The Color Wheel

Ever wondered how designers find the perfect color combination? Well, they use color theory—a blend of art and science—to determine which colors complement each other.

And, understanding the fundamentals of color theory is also crucial for effective data visualization. Because remember, colors evoke emotions, convey meaning, and influence perceptions.

Check out this 1-minute video called "A Brief Lesson on Color Theory" by Rhea Lelina Manglapus, which gives an amazing introduction to color theory.




The Color Wheel, which is based on color theory, showcases the relationship between colors. Colors that blend well together are known as color harmonies. A color wheel with its rules for color combinations, helps us find harmonies by positioning colors effectively for a pleasing effect.


There are two main color wheels: RYB (red, yellow, blue) for artists working with paints and RGB (red, green, blue) for online use, where colors are mixed in light on screens (like in TV or computers).


And luckily for us, there are bunch of (free) tools available online that can guide you in selecting colors that work well together and create a harmonious balance. It’s like having your own personal stylist, but for reports!


Here are some of my go-to tools:


Colors have different meaning and evoke emotions

It's important to note that colors can have different meaning and their meaning can vary significantly across cultures. Moreover, colors can evoke a range of emotions, contributing to the overall impact of your Power BI reports. For example, in Western cultures, red is often associated with passion or danger, while in some Asian cultures, it represents good luck and happiness.


It's important to research and understand the different cultural interpretations when selecting your color palette. What is the impact that you would like to make? Are there specific colors that resonate positively with your target audience?


The 60-30-10 Rule

When it comes to color, keep it simple and intentional. Colors shouldn't overwhelm the user.


One popular rule of thumb is the 60-30-10 rule, which suggests using three main colors in your design:

  • 60% - dominant color

  • 30% - secondary color

  • 10% - accent color


For example, you can use the dominant color as the background, the secondary color for headings and subheadings, and the accent color for adding emphasis and capturing the user’s attention.


If you would need to introduce more than 3 colors, split the dominant color (or the secondary color, but never the accent!)


Enhancing accessibility in your reports with color

To ensure that your reports are inclusive to everyone, including users with visual impairments, consider using high contrast and color blind-friendly palettes.

  • Color-blind-friendly palette: Consider using a palette that is inclusive. Tools like Adobe Color Accessibility Tools (again, I know, but it's not a paid ad) offer the option to check if the chosen palette is color-blind safe. What's more, you can also see how people with different visual impairments perceive the chosen colors.

  • Microsoft's Power BI also has some built-in accessible themes that you can use. Under the "View" tab you can explore all the themes and expand to see the accessible ones.

Using brand colors

When incorporating brand colors, you're not just reinforcing brand identity; you're also ensuring consistency across your organization's visual communication. Brand colors become a familiar and distinctive element for your audience.


However, if you have a single dominant brand color, consider using it as an accent color rather than the primary hue throughout the entire report. For the rest of the report, aim to create a complementary palette or explore different shades of the same color, especially if the original tone is too bold or bright. This approach ensures a harmonious blend of brand representation and overall visual appeal.


Concluding remarks

When it comes to colors, less is more. Keep your designs simple and intuitive. And remember, the use of color in Power BI reports is not just about aesthetics; it's about improving comprehension, drawing attention to key insights, and ensuring accessibility to all users.
