If you're on Pinterest, type in the search bar a colour and nursery - there should be more to see. But I agree, grey seems to be "in" now. As much as I do think grey rooms look nice, it's not very appealing for a child's room
And adore the slightly salmony dried plaster type colour on the middle picture. Can't get it past DP though sadly. So my house is totally white and I use pictures and plants and soft furnishings to add colour.
