I have an existing Crypto view app that already works well on the backend, but its interface still uses a dated light palette. I’d like a designer-developer who can swap the current colors for a polished dark theme without touching any logic. Scope • Audit the current screens and components to spot every element that needs recoloring. • Produce a cohesive dark-mode palette (backgrounds, typography, primary/secondary accents, charts). • Update the CSS/Sass (or relevant style files) so every page renders correctly in the new scheme. • Preserve readability and accessibility; contrast ratios should remain WCAG AA or better. • Deliver cleaned, well-commented code plus a quick before/after guide so I can verify changes quickly. Tech stack The project is built with standard web tech (HTML, CSS, JavaScript) and a React front end, so familiarity with React theming tools such as styled-components, Material-UI theming, or CSS variables will help you move fast. I’m aiming for a lean engagement that focuses only on the visual layer. If you’ve rolled out dark themes before and can deliver crisp, consistent styling, let’s talk.
