A colour-palette manager with a hex-to-name matching engine, built on ASP.NET Core and Entity Framework.
About
A colour-palette manager where users collect and organise palettes with per-collection privacy controls, built on an ASP.NET Core 8 and Entity Framework Core API backed by PostgreSQL, paired with a React frontend in a companion repo. I led the API, designing the Entity Framework Core data model (including a ColourCollection join table with explicit ordering and a full migrations history) and the privacy-filtered collections-by-user endpoints scoped to the authenticated user. ColourSearch.cs is the part I am most proud of: type "bright light reddish orange" and it returns the correct hex. It converts between hex, RGB and HSL, then traverses the named-colour space by perceptual distance to resolve any description to its nearest match. The REST API is documented with Swagger and secured with ASP.NET Identity authentication.
Highlights
- Colour-matching engine (ColourSearch.cs): hex to RGB to HSL conversion with validation and nearest-colour name resolution, letting the app name arbitrary hex codes.
- Entity Framework Core data model with a ColourCollection join table, explicit ordering, and a full migrations history.
- Privacy-filtered collections-by-user endpoints: public/private visibility per collection, scoped to the authenticated user.
- Colour DTOs with serialisation for frontend consumption, enabling colour operations to be driven from the React UI without coupling the API to presentation logic.
- Swagger-documented REST API on ASP.NET Core 8 with ASP.NET Identity authentication.
