/*** * Converts a decimal RGB color string ("255255000") to an hexadecimal RGB color string ("#FFFF00"). * Input string is expected to be 9 length without separation characters. * Output string is in CSS style ("#FFFF00") ***/ Let ([ HexCharset = "0123456789ABCDEF" ; RDec = Middle ( Dec ; 1 ; 3 ) ; GDec = Middle ( Dec ; 4 ; 3 ) ; BDec = Middle ( Dec ; 7 ; 3 ) ; R = Middle ( HexCharset ; Truncate ( RDec / 16 ; 0 ) + 1 ; 1 ) & Middle ( HexCharset ; Mod ( RDec ; 16 ) + 1 ; 1 ) ; G = Middle ( HexCharset ; Truncate ( GDec / 16 ; 0 ) + 1 ; 1 ) & Middle ( HexCharset ; Mod ( GDec ; 16 ) + 1 ; 1 ) ; B = Middle ( HexCharset ; Truncate ( BDec / 16 ; 0 ) + 1 ; 1 ) & Middle ( HexCharset ; Mod ( BDec ; 16 ) + 1 ; 1 ) ]; "#" & R & G & B ) // End Let Click to copy

Each component is treated separately: first it's read from input, then converted from decimal to hexadecimal. Very scholastic.
Each component then is appended to the output string that begins with '#' to fit CSS format.
