10/// An expressive color scheme with creative color manipulation.
11///
12/// Uses complex color transformations to create unexpected but harmonious combinations.
13/// Best for distinctive, artistic designs.
14///
15/// # Example
16///
17/// ```
18/// use mcu_scheme::SchemeExpressive;
19/// use mcu_hct::Hct;
20///
21/// let source = Hct::from_int(0xFF0000FF); // Blue
22/// let scheme = SchemeExpressive::new(source, false, 0.0);
23/// assert!(!scheme.is_dark);
24/// ```
