When choosing a color palette for your brochure, it's important to consider the mood you want to create. Different colors can have different psychological effects on people, depending on culture, context, and personal preferences. For example, red can be associated with passion and energy, but also danger and violence. Yellow can be associated with happiness and optimism, but also caution and anxiety. Generally speaking, warm colors (red, orange, yellow) tend to be stimulating and attention-grabbing, good for creating a sense of urgency or enthusiasm. Cool colors (blue, green, purple) are calming and soothing, good for creating trust or tranquility. Neutral colors (black, white, gray, brown) are versatile and sophisticated, good for creating a sense of balance or authority.
