# Customise Theme

Your Sayy AImployee is not just functional, it is an extension of your brand. From visual theme to voice and tone, you can fine-tune the way it looks, feels, and sounds to match your unique identity. This is especially important for modern-day brands as you don't want a chatbot that feels like a force fit and doesn't remind the user of your business.

#### 🖼️ Display Theme

Set the overall appearance of your agent by choosing between a light or dark theme. This controls the background and layout feel, perfect for aligning with your brand’s mood or audience preference.

#### 🎨 Brand Colors

Choose from preset color palettes or fully customize your primary and accent colors. This is where you bring your brand identity to life, giving your AImployee a visual style that feels instantly familiar to your audience.

#### 🔤 Font Style

Select from clean, modern font options to match your tone, whether that is casual, playful, bold, or professional. Font choice influences readability and personality, so it plays a key role in how your chat feels.
