• HSVColorPickerArea / HSLColorPickerArea replaced by exported HSVColorSlider / HSLColorSlider.
• Checkerboard painter consolidated as AlphaPainter (replaces ad-hoc checkboard usage in the old file).
• Old helper composites like ColorPickerSet, MiniColorPickerSet, and popup/dialog variants were removed in favor of ColorInput + ColorPicker with prompt modes.

Color system and utilities

• Reorganized existing color utilities under the new color module; no functional changes to ColorDerivative or colorToHex. Added gradient types (linear, radial, sweep) for future composition.

Color Picker

• Replaced legacy ColorPicker implementation with a new slider-based picker using dedicated HSV/HSL painters and alpha checkerboard. Supports live editing via onChanging/onChanged and consistent display using an effective in-progress value.
• Added modes for RGB, HSV, HSL, and HEX; optional alpha controls; horizontal/vertical orientation; spacing and slider size theming via ColorPickerTheme.

Color Input

• New ColorInput widget with ColorInputController and theming. Integrates popover/dialog prompting, optional HEX label display, orientation, and EyeDropper integration. ControlledColorInput variant for form integration.

Eye Dropper and History

• Added screen color picker (pickColorFromScreen and ColorPickingLayer) with magnified preview and label; added RecentColorsScope and ColorHistoryGrid to persist and pick previously sampled colors.

API exports

• Public exports updated to include color utilities, ColorPicker, ColorInput, EyeDropper, History, and slider widgets.

i18n and formatting

• Added colorPickerTabHEX localization key and TextInputFormatters.hex (supports optional hash prefix) for safe HEX input. If you provide a custom localization, add this new key.
