Code:
$ cat ref.txt
2,66,4,Pink
1,B,3,Tennis

Code:
awk -F, '
        NR == FNR {
                S[$1] = $2 FS $3 FS $4
                next
        }
        {
                n = split ( $0, U )

                for ( k in S )
                {
                        m = split ( S[k], T )

                        if ( T[1] == U[k] )
                        {
                                for ( i = 1; i <= NF; i++ )
                                {
                                        if ( i == T[2] )
                                                $i = T[3]
                                }
                        }
