A JavaScript library for generating random pleasing colors and creating color schemes using HSV color space.
Please.js is a JavaScript library that generates random pleasing colors and creates color schemes programmatically. It uses the HSV color space to produce harmonious colors, helping developers quickly add visually appealing color palettes to their projects without manual color picking.
Frontend developers, UI/UX designers, and creative coders who need programmatic color generation for web applications, data visualizations, or design tools.
Developers choose Please.js for its simplicity, golden ratio-based default generation for aesthetic colors, and built-in support for multiple color schemes and formats—all in a lightweight, dependency-free library.

Defaults to using the golden ratio in make_color() to ensure generated colors are visually harmonious, as explicitly stated in the README for pleasing results.
Supports six scheme types including complementary and triadic, allowing for easy palette creation from a base HSV color with minimal configuration.
Returns colors in multiple formats like hex, RGB objects, and HSV objects, providing versatility for different programming needs, as detailed in the options.
Recognizes 146 standard HTML color names through functions like NAME_to_HEX(), enabling quick base color selection without manual conversion.
Lacks features for calculating color contrast ratios or ensuring WCAG compliance, which is critical for accessible web design but not mentioned in the README.
Only offers fixed scheme types without options for custom angular offsets or advanced color theory manipulations, restricting flexibility for unique designs.
Requires base colors in HSV format for make_scheme(), which may add an extra conversion step for developers more familiar with RGB or HEX color spaces.
