Look at post #244 from Andy. SW45K has a negative duv value thus the rosy tint. SW35 is pretty much spot on with a duv of almost 0. The bigger the negative duv value is, the rosier it is. Others feel the SW35 has a slight rosy hue to it mixed with a warmer temperature tint (myself included) but the SW45K takes the #1 spot in rosiness.
