Wideband (ww) lengthens (widens) the middle band on the agouti coat.

On the agouti, full-color, non-extention coat this creates a richer, red coloring. Other coat changes include the following

1. Reduces smut
2. Eliminates the grey undertone on the belly next to the skin
3. When coupled with high Rufus, it allows the red/cream tones to come into the agouti marks (eye circles, belly, inner ears, etc.) rather than those staying white.
