Class Method Details

.convert(xyz_color) ⇒ Abachrome::Color

Converts a color from XYZ color space to sRGB color space.

This method first converts XYZ to linear RGB using the inverse transformation matrix, then applies gamma correction to convert to sRGB. The XYZ color space is the CIE 1931 color space that forms the basis for most other color space definitions and serves as a device-independent reference.

the same alpha as the input color
