// Match types with concepts (1 to many)
type Color1 = int * int * int
type Color2 = Red | Green | Blue
type Color3 = Red=1 | Green=2 | Blue=3
type Color4 = { Red: int; Green: int; Blue: int }
type Color5 = {| Red: int; Green: int; Blue: int |}
type Color6 = Color of Red: int * Green: int * Blue: int
type Color7 =
    | RGB of {| Red: int; Green: int; Blue: int |}
    | HSL of {| Hue: int; Saturation: int; Lightness: int |}

// A. Alias
// B. Enum
// C. Record
// D. Record anonyme
// E. Single-case union
// F. Union
// G. Union enum-like
// H. Tuple

Answer

Types	Concepts
type Color1 = int * int * int	H. Tuple + A. Alias
type Color2 = Red ∣ Green ∣ Blue	G. Union enum-like
type Color3 = Red=1 ∣ Green=2 ∣ Blue=3	B. Enum
type Color4 = { Red: int; Green: int… }	C. Record
type Color5 = {∣ Red: int; Green: int… ∣}	D. Anonymous Record + A. Alias
type Color6 = Color of Red: int * …	E. Single-case union + H. Tuple
type Color7 = RGB of {∣…∣} ∣ HSL of {∣…∣}	F. Union + D. Anonymous Record

Conclusion

Lots of ways to model!
