It is remarked that within the gauge theory of physical color (integer-charge quarks), one expects to see significant rises in neutral-current parameters (approx. =40--45 % in sigma/sup ..nu..//sub NC/, approx. =60--65 % in sigma/sub NC//sup nu-bar /, approx. =20 % in R/sub ..nu../, and approx. =10 % in R/sub nu-bar/) due to color excitation above color threshold. This pattern of rises is characteristic of the color-excitation hypothesis alone; it cannot be attributed to new-flavor excitation within the gauge framework. It is pointed out that within the constraints of renormalizable gauge interactions new-flavor excitation may (under very special circumstances involving an extension of the SU(2)/sub w/ x U(1) gauge structure) lead to rises in the neutral-current parameters; however, the corresponding pattern of rises (i.e., rises in ..nu..N versus nu-barN) is distinct from that due to color excitation.
