4.1.0: The Dominant Wavelength Release

• Add dominant wavelength
• Add excitation purity
• Add imaginary colour detection
• Add construction from chromaticity

🎁 NuGet Package

4.0.0: The Hue Span & Spectral Power Release

• Add hue spans to allow different hue interpolation methods (shorter, longer, increasing, decreasing)
• Allow colours with different configurations to be mixed
• Update to more modern and accurate temperature algorithm
