Enter a color and convert it into multiple useful representations, including hex, RGB, RGBA, HSL, and HSLA. Blissum includes options for uppercase hex and alpha output, and shows a structured conversion summary so designers and developers can copy the exact format they need. It is a local color conversion tool for style guides, CSS work, SwiftUI values, and design handoff.
Blissum groups everyday code, text, data, and web utilities into one local app for Mac, iPhone, and iPad, which is especially useful where iOS has fewer native developer-tool options.
