Fails to Build due to PlayerSettings not existing

When building, a compiler error is thrown.

Assets\Shapes\Scripts\Runtime\Utils\ShapesExtensions.cs(27,63): error CS0103: The name 'PlayerSettings' does not exist in the current context

The line in question is this one:

internal static Color ColorSpaceAdjusted( this Color c ) => PlayerSettings.colorSpace == ColorSpace.Linear ? c.linear : c;
