Consider, I have a disk colored in “LAB” color space. When I convert the graphics into image object it is by default getting converted into “RGB” color space.
ImageColorSpace@Image[Graphics[{LABColor[0.4, 0.6, 0.8], Disk[]}]]
“RGB”
If I now convert it back to “LAB” color space,
ColorConvert[ Image[Graphics[{LABColor[0.4, 0.6, 0.8], Disk[]}]], "LAB"]
The color value that I get is
{0.437891, 0.566411, 0.478353}
(* Sorry, this was a mistake on my part. Duely corrected after following the answer by Theelepel *)
How can I get the original color value in the “LAB” color space?
Updated question: If the original color value is not known and I am given only with the final Graphics object showing RGB color value, How can I retrieve the original LAB color value?
