Modern Logo With Versatile Palette

I’m commissioning a fresh, modern logo and would like to explore different colour moods to see what best captures the brand’s personality. Please provide concept variations that intentionally test the following palettes:
• Bright colours
• Pastel colours
• Monochrome treatments

Clean lines, balanced typography, and a design that scales well across digital and print media are essential. Once a concept is approved, I’ll need the final artwork delivered as layered vector files (AI or SVG) plus high-resolution PNG/JPG exports for immediate use.
