Based on your query for a spreadsheet color theme, I’ve created a versatile color palette that can help differentiate various elements like inputs, titles, and headings. This palette includes distinct colors for clarity and organization.

 <Spreadsheet Color Theme>
1. Input Fields - 
                            
                            #D1E7DD
                         - A soft, calming green that indicates editable fields and encourages user interaction.
2. Titles - 
                            
                            #0D6EFD
                         - A bright blue that stands out, perfect for titles to grab attention and signify importance.
3. Headings - 
                            
                            #FFC107
                         - A warm amber that highlights headings, making them easily recognizable without being too harsh.
4. Background - 
                            
                            #F8F9FA
                         - A light gray that provides a neutral base, ensuring that text and inputs are easy to read.
5. Disabled Fields - 
                            
                            #E2E3E5
                         - A muted gray that signals non-editable areas, suggesting a lack of interaction without being overly stark.

This color palette is designed to enhance usability while maintaining a professional appearance.
