Pictures attached for 3 bathrooms, first 2 are from same bath

I've seen a lot of photos and I have come to realise that I really like the pastel/muted color pallete and have also come to know that they are good for small rooms. I really liked nickel grey and silver grey. Do both of these colors also belong to pastel color pallete? I am not able to find a separate section for pastel color pallete on asian paints' website. So it's difficult to find similar colors. Thanks for helping me.

We are located in the Pacific Northwest and want to update our office and shop. Inside our walls are tan with tan tile and the horrendous golden oak doors and trim.

When the sunlight doesn't touch the wall surface, white tends to look grey and dull. Window Walls tend to have this problem especially if none of the adjacent walls have windows. One trick to liven up the window wall is to paint it in a rich, warm yellow tone. As shown in the attached picture. But don't paint any other wall in the room in this colour, as it will be overwhelming.
