Main & Sub-Brand Logo Design

I need two cohesive logos designed: one that represents my primary brand and a second that serves as its sub-brand. Both must feel bold and eye-catching, yet the sub-brand should stand on its own with a fresh colour palette and a distinct symbol while still echoing the overall style of the main mark. Here’s how I picture the process and final hand-off: • Primary logo: vector artwork in full colour, black, and white versions • Sub-brand logo: vector artwork in its own colours plus monochrome versions • Complete font and colour specifications for both • High-resolution PNG and SVG exports ready for web, print, and social media • A brief style-guide page that shows how the two marks relate If you have recent examples of bold, attention-grabbing identities—or ideas on how to balance shared style with unique accents—please include them so I can see your approach.
