Squarespace Color & Font Refresh

My Squarespace site works well, yet its visual tone feels a little dated. I want a crisp, modern-minimalist update that focuses only on the color palette and typography. The existing text, images, layout, and platform stay exactly as they are—please don’t suggest switching to WordPress.

What I need:
• A refined, harmonious color palette applied through the site’s design panel.
• Contemporary, easy-to-read font pairings that match the new palette.
• Implementation directly in Squarespace, with responsive checks on desktop, tablet, and mobile before hand-off.

Process I have in mind:
1. Present two style concepts (palette + fonts) that fit a clean, minimalist aesthetic.
2. After I choose one, roll it out across all pages and test for consistency and accessibility.
3. Provide a quick walkthrough or short Loom video so I can adjust styles later if needed.

Please share relevant Squarespace experience—especially any projects where you refreshed colors and fonts within the platform. That background will help me decide quickly and get this refresh live without disrupting site content.
