Material Design Colour Theme Setup (Light & Dark Mode)

I’m looking for a designer experienced with Material Design 3 and Figma theme systems to help set up a full colour theme for an existing project.

The design is already complete, I just need help with the Material theme setup in Figma:

- Define a full colour palette (light and dark themes) using our existing primary colour as the base

- Set up colour variables for all states (high and low contrast, surface, background, on-surface, outline, etc.)

- Ensure the theme works correctly across all Material components

- Optionally export the colour variables as JSON for dev handoff

- You can suggest adjustments to improve contrast or balance, but keep the general direction of the primary colour

No UI design needed, this is purely a colour system and variable setup task in Figma.

Budget:
Fixed price: £75 (suitable for a focused Figma-based theme setup).
If you can also handle the JSON export and minor contrast refinements, I’m open to £100 for a quick, high-quality turnaround.
