Some common mistakes people make when choosing brand colors include: Choosing too many colors: It's better to choose a few key colors that will be used throughout your branding. This will help to create a cohesive and consistent visual identity. Using colors that are too similar: Using colors that are too similar can make your branding look boring and unmemorable. It is important to use colors that have a good contrast to create a visually appealing and memorable brand. Not updating their brand colors: As your brand evolves, you may need to update your brand colors. This is especially important if your target audience changes or if your brand's personality changes.
