Hi, I've a background in color theory from years ago but the last time I used Mathematica was probably v.2. My concern is with colors, not images. I've been reading and experimenting with the documentation here: https://reference.wolfram.com/language/guide/Colors.html

Now lets suppose I have a color from somewhere; e.g.

mycolor = Blend[{Purple, LightBlue}, 0.5] ;

1. Does this have an absolute internal representation or is it relative to some colorspace -- and if so, how do I determine which one?
2. How do I determine the color coordinates of an arbitrary color in a given colorspace? For example, what procedure will yield the (approximate) RGB coordinates of mycolor?

Thank you for your replies.
