Italian to English…

Dichiara = Let
Refila = Trim
CercaeSost = Substitute
Mezzo = Middle
Posizione = Position
Sinistra = Left
Destra = Right
Casi = Case
Lunghezza = Length
RicavaComeTesto = GetAsText

I'm pretty sure I got those all right!

So in English this is


Let ([

Hex = Trim ( Substitute ( Hex ; "#" ; "" ) ) ;
HexCharset = "0123456789ABCDEF" ;
RHex = Middle ( Hex ; 1 ; 2 ) ;
GHex = Middle ( Hex ; 3 ; 2 ) ;
BHex = Middle ( Hex ; 5 ; 2 ) ;
R = 16 * ( Position ( HexCharset ; Left ( RHex ; 1 ) ; 1 ; 1 ) - 1 ) + ( Position ( HexCharset ; Right ( RHex ; 1 ) ; 1 ; 1 ) - 1 ) ;
G = 16 * ( Position ( HexCharset ; Left ( GHex ; 1 ) ; 1 ; 1 ) - 1 ) + ( Position ( HexCharset ; Right ( GHex ; 1 ) ; 1 ; 1 ) - 1 ) ;
B = 16 * ( Position ( HexCharset ; Left ( BHex ; 1 ) ; 1 ; 1 ) - 1 ) + ( Position ( HexCharset ; Right ( BHex ; 1 ) ; 1 ; 1 ) - 1 ) ];

// R
Case (
Length ( R ) = 1 ; "00" ;
Length ( R ) = 2 ; "0" ;
) & GetAsText ( R ) &

// G
Case (
Length ( G ) = 1 ; "00" ;
Length ( G ) = 2 ; "0" ;
) & GetAsText ( G ) &

// B
Case (
Length ( B ) = 1 ; "00" ;
Length ( B ) = 2 ; "0" ;
) & GetAsText ( B )

) // End Let
