fromLABa
Converts a color from the LABa color space to the LCHABa color space.
The conversion maps the lightness (l) from LABa to LCHABa, calculates the chroma (c) as the magnitude of the a and b components, and computes the hue (h) as the angle of the vector formed by the a and b components. The alpha and reference white values are retained from the original LABa color.
Return
A ColorLCHABa instance representing the color in the LCHABa color space.
Parameters
laba
The color in the LABa color space to convert.
