# DroppyGlassControl

The Liquid Glass control recipe: the fill vocabulary, the ink, and the wash for one state.

`enum DroppyGlassControl`

The Liquid Glass control recipe: the fill vocabulary, the ink, and the wash for one state. `DroppyGlassControlChrome` draws it; the button styles in this module are built on it.

## Cases

### DroppyGlassControl.Fill.veil

`case veil`

Plain Liquid Glass. The neutral control.

### DroppyGlassControl.Fill.tinted(_:)

`case tinted(Color)`

The colour washed over the glass, for a confirming or accent action.

### DroppyGlassControl.Fill.solid(_:)

`case solid(Color)`

The colour as an opaque disc or pill, no glass: a classic notch puck beside black nav capsules, a green success flash.

## Type methods

### fill(for:)

`static func fill(for color: Color?) -> Fill`

Neutral when `color` is nil or is the highlight the user picked in Settings, Theming (the default preset resolves to the label colour, so a "tinted" pill would wash grey over the glass); tinted otherwise.

### ink(for:isEnabled:)

`static func ink(for fill: Fill, isEnabled: Bool = true) -> Color`

Label colour for a control painted with `fill`.

### isThemeHighlight(_:)

`static func isThemeHighlight(_ color: Color) -> Bool`

True when `color` is the app highlight from Settings, Theming.

### needsDarkInk(_:)

`static func needsDarkInk(_ color: Color) -> Bool`

Dark ink on a light solid fill: luminance decides.

### neutralInk(isEnabled:)

`static func neutralInk(isEnabled: Bool = true) -> Color`

The reference ink: the adaptive label colour, dimmed when disabled.

### wash(for:isHovering:isPressed:isEnabled:)

`static func wash(for fill: Fill, isHovering: Bool, isPressed: Bool, isEnabled: Bool) -> Color`

The wash over the glass for one state: nothing at rest on the neutral control and a whisper under the pointer, the accent on a tinted one, the colour itself on a solid one.
