The answer to this question is... complicated.

Colorspace is the SPACE of colors (as the name suggests) and colormatrix 
is ​​a... conversion method (between two colormatrixes)

For example, imagine colorspace as range: the main range of computer 
colors 0-255 shades. As you know, the classic TV range is narrower, 
16-235. However, "today's" advanced gamuts are much much wider.

On the other hand, colormatrix: is like a color chart in a given 
colorspace/range - it's something like (!!!) a way to convert CMYK 
colors to RGB or convert color to gray - because depending on the way / 
colormatrix, medium gray can be #777, #707070 or #777777 or #7f7f7f etc.

I wrote it briefly and figuratively.
Maybe someone can explain it better and more understandably...
