+**CLASS**
+
+# `GrayscaleColor`
+
+```swift
+public class GrayscaleColor: NSObject, NSCopying, Codable
+```
+
+> A model class representing grayscale colors. The white component can hold values between 0.0 and 255.0 while the alphavalue has a maximum value of 100.0.
+
+## Methods
+### `init(white:alpha:)`
+
+```swift
+public init(white: CGFloat, alpha: CGFloat)
+```
+
+> Creates a GrayscaleColor instance.
+>
+> - Parameter:
+> - white: The white component.
+> - alpha: The opacity component.
+
+### `copy(with:)`
+
+```swift
+public func copy(with _: NSZone? = nil) -> Any
+```
+
+> Creates a copy of the GrayscaleColor instance.
+>
+> - Returns: A copy of the GrayscaleColor instance.
+
+### `isEqual(_:)`
+
+```swift
+public override func isEqual(_ object: Any?) -> Bool
+```
+
+> Compares two GrayscaleColor instances with each other.
+>
+> - Parameter object: The GrayscaleColor to compare with.
+>
+> - Returns: 'true' if the instance is equal to the other GrayscaleColor instance, otherwise 'false''.
+
+#### Parameters
+
+| Name | Description |
+| ---- | ----------- |
+| object | The GrayscaleColor to compare with. |
