+## Logo Variations and Formats
+
+Digital products require flexible logo systems that adapt across contexts. Common formats include:
+
+- **Primary logo:** The full version, including both symbol and wordmark.
+- **Logomark only:** A standalone icon or symbol used when the full logo is unnecessary or unsuitable.
+- **Responsive logo:** A simplified version used in small spaces like navbars or tab icons.
+- **Monochrome or inverted logo:** Versions designed for dark mode, grayscale, or print compatibility.
+
+> **Note:** A logo must remain legible and balanced across formats, screen sizes, and accessibility contexts.
+
+## What does a Logo Communicate about a Brand
+
+A logo conveys subtle but powerful messages about the brand:
+
+- **Tone of voice:** A logo sets expectations — playful, professional, experimental, minimalist.
+- **Industry or domain cues:** Symbols, colors, and typefaces suggest alignment with sectors like education, health, or finance.
+- **Company values:** Visual traits signal identity — bold vs. quiet, modern vs. traditional, innovative vs. stable.
