Switzerland – given you want lots of blues / reds I am struggling a bit
Lenzerhiede links to Arosa now – Arosa I like a lot, resort is a 2hr drive from Zurich or a great 3hr train ride esp last hour on cog railway (some bag porterage between trains – 2 changes). Arosa doesn’t have the km of postes but together they do. Not been since the linking lift opened. Arosa is at 2000m and sunny but in Jan could be a challenge, horse drawn sledges (best looked at rather than ridden unless you’ve won lottery)
Crans Montana ?
Villars if snow is good (low and sunny but you are going in Jan)
Verbier and Zermatt imo are not what you are after.
Austria – it’s donkeys years since I have been anywhere except St Anton, the linked resort of St Christoph could work if you want quiet-ish, hotels only I recall.
