Colors can make or break your visual aids, whether they are slides, charts, graphs, or infographics. They can help you convey your message, highlight key points, create contrast, and evoke emotions. But how do you choose the best colors for your visual aids? Here are some tips to help you.
The first step is to consider who will see your visual aids and what their expectations, preferences, and needs are. Different colors can have different meanings and associations across cultures, industries, and contexts. For example, red can signify danger, passion, or power, depending on the situation. You want to avoid colors that might offend, confuse, or distract your audience. You also want to choose colors that suit the tone and purpose of your presentation. For example, bright and warm colors can be more engaging and energetic, while cool and muted colors can be more calming and professional.
It is important to take into consideration the type of message you are presenting and where you want to attract the attention. In my line of work, for example, I am mindful to use the colors of the company, so that I stay within its standards when it comes to what colors are appropriate. I agree that the purpose of the presentation plays a big role (i.e., Is the presentation to inform your audience or present facts? Are you expecting a decision to be made? etc.). Adding colors on the key words tied to the purpose of the presentation certainly makes a difference.
The second step is to use a color scheme that creates harmony, balance, and contrast in your visual aids. A color scheme is a set of colors that work well together and complement each other. There are different types of color schemes, such as monochromatic, analogous, complementary, triadic, and tetradic. You can use online tools or apps to generate color schemes based on your main color or theme. A good rule of thumb is to limit your color scheme to three to five colors and use them consistently throughout your visual aids.
The third step is to apply the 60-30-10 rule to distribute your colors in your visual aids. This rule is a guideline for creating visual hierarchy and emphasis in your design. It means that you use 60% of your main color, 30% of your secondary color, and 10% of your accent color in your visual aids. The main color is the dominant color that sets the mood and tone of your presentation. The secondary color is the supporting color that creates contrast and variation. The accent color is the highlight color that draws attention and adds interest. For example, you can use a dark blue as your main color, a light blue as your secondary color, and a yellow as your accent color.
The fourth step is to consider accessibility and readability in your color choices. Accessibility means that your visual aids are easy to see and understand for people with different abilities and devices. Readability means that your text and graphics are clear and legible against the background color. You want to avoid colors that might cause eye strain, glare, or confusion for your audience. You also want to use colors that have enough contrast and saturation to stand out and convey information. For example, you can use a contrast checker tool to test your color combinations and ensure that they meet the web content accessibility guidelines (WCAG).
The fifth step is to test your colors and see how they look on different screens and devices. Colors can vary depending on the brightness, resolution, and settings of your display. You want to make sure that your colors are consistent and accurate across different platforms and formats. You can use online tools or apps to preview your colors and adjust them if needed. You can also print out your visual aids or project them on a screen and get feedback from others.
The sixth and final step is to follow some best practices and tips for using colors in your visual aids. It's important to use colors sparingly and strategically, as too many or randomly used colors can overload your visual aids. Additionally, make sure to use colors that match your brand identity, data, content, and emotions. For instance, green can be used for positive results, red for negative results, and pink for compassion. All in all, using the right colors can help you highlight important information, create contrast, and guide the eye.
