Vibrant Background & Button Recolor

I’m refreshing an existing interface and need the background and all interactive buttons swapped to a bright, vibrant palette. I already have the exact hex codes ready, so your task is to apply those colors cleanly across the layout, ensuring contrast, readability and overall consistency with the current typography and imagery.

Deliverables:
• Updated style sheet (or equivalent) with the new background and button colors applied.
• Quick before-and-after screenshots so I can visually confirm the changes.

Please handle any hover, active or disabled states the buttons use, double-checking that they remain accessible and visually cohesive. If anything looks off once applied, a brief note on recommended tweaks will be appreciated.
