The ToRGB command returns the RGB floats from $0.$ to $1.0$ of a Color object as a list.

$p≔\mathrm{ColorTools}:-\mathrm{Color}\left(''pink''\right)$

$p≔⟨RGB\; :\; 1\; 0.753\; 0.796⟩$

$\mathrm{ToRGB}\left(p\right)$

$\left[1.0000000\,0.75294118\,0.79607843\right]$

$r≔\mathrm{ColorTools}:-\mathrm{Color}\left(''HSV''\,''red''\right)$

$r≔⟨HSV\; :\; 0\; 1\; 1⟩$

$\mathrm{ToRGB}\left(r\right)$

$\left[1.0000000\,0.\,0.\right]$

The ColorTools[Color][ToRGB] command was introduced in Maple 2017.
