Get color information and determine color coordinates?

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.

Purple, Lightblue and their blends are all RGB colors

Purple // FullForm

returns RGBColor[0.5,0,0.5]

LightBlue//FullForm

returns RGBColor[0.87,0.94,1] and

Blend[{Purple,LightBlue},0.5]//FullForm

returns RGBColor[0.685,0.47,0.75]`

I hope this answers your question.
