The API uses a builder-style interface for flexible palette configuration, supporting multiple input formats, color vision deficiency simulation, and perceptual color difference metrics. Full documentation is available at https://jolars.github.io/qualpal/. This library is also available as - an R package called qualpalr, - as a python package called qualpal, - and as a web application at qualpal.cc. Features - Automatic selection of color palettes using perceptual color difference metrics - Color vision deficiency simulation for accessible palette design - Multiple input formats: RGB values, hex strings, HSL ranges, built-in palettes - Fast algorithms for large color spaces - Builder-style C++ API for flexible palette configuration - Web-Based Interface for simple and interactive color palette generation Table of Contents - Features - Motivation - R Package - Web App - Quick Start - Installation - Usage Examples - Contributing - Versioning - License Motivation When visualizing categorical data, it is often necessary to select a set of distinct colors that are easily distinguishable from each other. This is especially important for accessibility, as many people have color vision deficiencies (CVD) that make it difficult to distinguish certain colors. Qualpal aims to provide a simple and effective way to generate such color palettes, ensuri","default_branch":null,"files":null,"tree":[],"storefront":"/r/jolars","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/jolars/qualpal/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
