Website Background Color Update

I need the current background of my website switched to a new solid color across every page. The job is purely a color change—no gradients, patterns, graphics, or other design elements are required—so it should be a straightforward CSS / style-sheet update.

Here’s what I expect:
• Inspect the existing site structure, locate the relevant style rules, and apply the new color so it displays consistently on desktop and mobile browsers.
• Make sure there are no clashes with existing text, icons, or UI components; legibility and contrast must remain intact.
• Provide the updated CSS (or theme file) along with a brief note of exactly what was changed for future reference.
• Test in the latest versions of Chrome, Firefox, Safari, and Edge before delivery.

The site is built with standard HTML-CSS; no build tools or frameworks are in play, so a quick turnaround is possible. Once you’re ready, let me know any information you need—URL, access credentials, or color values—and I’ll supply them right away.
