Note: Color conversion uses the CIE L*a*b* to sRGB transformation with D65 illuminant (standard daylight). The displayed color is an approximation and may vary depending on your screen calibration.
Reference: CIE 1976 L*a*b* color space (CIELAB) - ISO/CIE 11664-4:2019
Formulas:
• a* = C* × cos(h° in radians)
• b* = C* × sin(h° in radians)
