## Description

Pickr is a dependency-free JavaScript color picker library and multi-format color converter. It provides a visual interface for selecting colors and transforming them between HEX, RGB, HSL, and CMYK representations.

The library is designed as a themed UI component that can attach to and function within web shadow roots. It supports customizable visual styles and layout applications to align with various CSS frameworks and design systems.

Capability areas include visual color selection with alpha channel opacity control, the management of preset color swatches, and an event-driven callback system for handling user interactions. It also features coordinate-based color mapping and scroll-based numeric value adjustments.
