Trouble with color scheme with Windows 10 Scanner

[paswd]

Hello! Windows 10 default scanner has a pretty (for me) interface, but it's a little stupid: I can't select color mode in this app. And, if I don't set color mode in SANE, it will be gray as default. So, scanned image in Windows 10 Scanner is always gray. Maybe it will be better to set default color scheme while driver setup and later set mode directly in each query? Thanks
