Based on your request for an academic tool website that conveys a sense of technology with a touch of liveliness, I’ve created a web-friendly color palette that follows WCAG 2.1 color contrast compliance. This palette includes colors for the background, text, primary action, secondary action, and accent.

 <Academic Tech Vibe>
1. Background - 
                            
                            #F4F6F9
                         - A light, soft gray that provides a clean and neutral backdrop for content, enhancing readability and reducing eye strain.
2. Text - 
                            
                            #1F2A44
                         - A deep navy blue that ensures high contrast against the background, making the text easy to read and giving a professional look.
3. Primary Action - 
                            
                            #007BFF
                         - A vibrant blue that stands out and encourages user interaction, suitable for buttons and links that require attention.
4. Secondary Action - 
                            
                            #28A745
                         - A lively green that complements the primary action color, perfect for secondary buttons and actions without overwhelming the user.
5. Accent - 
                            
                            #FFC107
                         - A warm amber that adds a hint of liveliness, ideal for highlighting important information or elements within the interface.

This color palette combines a professional and academic feel with vibrant accents, reflecting both technology and liveliness.
