Document Background Color Adjustment

I need the colours of every background and graphic shape in my document updated to a new palette I will supply. Text, headings, photos, and logos should remain untouched; only the fills, gradients, or pattern colours behind and around them have to shift.

I will provide the original file (likely in PDF, AI, or PSD format—let me know which you prefer) together with the exact HEX values for each replacement colour. The finished document must come back in the same editable format plus a high-resolution PDF preview so I can review the result quickly.

Please ensure:
• Every background or shape—no matter the page or layer—uses the new palette consistently.
• No resolution loss, compression artefacts, or unintended colour shifts appear elsewhere.
• Turnaround is fast; I’m aiming to approve final colours within 48 hours of project start.

If this is straightforward for you, just outline the software you’ll work in (Photoshop, Illustrator, InDesign, etc.) and your estimated timeline, and we can get started right away.
