Dereddened the V−J (triangles), V−H (circles), and V−K (squares) colors for several supernovae. We have determined the mean residuals of those data with respect to unreddened loci derived from data used for Paper I. Except for SN 1998bu we have restricted the data to 0 ≤ t ≤ 27 days after the time of B‐band maximum. We have horizontally offset the J‐band point for SN 2000ce for plotting purposes. The solid line and dashed line are naive connect‐the‐dots "fits" to the V−H and V−K data, respectively. This figure shows that the mean residual is near zero for V−K over a range of luminosity at maximum. Overluminous slowly declining supernovae such as 1999aa and 1999gp are intrinsically bluer in V–near‐IR color indices than more rapidly declining objects are. More rapidly declining objects such as SN 2000bk have redder colors than the midrange decliners.
