colors are a personal thing, one tile I really like is a very dark sort of royal blue or cobalt blue, and I like tangerine orange. or butter yellow with it.
wall colors are easy to change. tile is not. I try not to go too loud because loud colors can affect the resale value. my house is orange but it is an earthy tone and not a strong disturbing color, the trim is all brick red. That combination fits the era, but there are very few orange houses. The tangerine I used is actually very similar in color to the finished color of Douglas fir. in most rooms I put a hint of the wall color in the ceiling paint and it has an effect with reflection , hides the line between the ceiling and wall color. I can't stand pink. I was convinced to paint one room baby blue. Hated it so I changed it. I htink if you use that tile it will need some other wall color or something else to compliment it. It feels 50's to me , reminds me of a two tone 57 Chev in aqua blue or almost turquoise and creme white.
I think if you follow auto colors it helps show what was kind of trending in different eras. you wont really find too many old 30's and 40's cars in weird bright outlandish colors. into the 50's they got louder. now they are all metallic silver. sometimes I find radios and things in certain sort of olive green and know it dates to about mid 50's but did not seem too popular earlier or later than a certain date. olive seemed to return in combination of fall colors, orange red etc as a sort of 70's theme.
I hate that stark Ikea white, they use a lot of today.. I dont have much furniture that is blue so anythign blue seems to not fit my house. One room can be quite different than others though. It's not necessarily a bad thing if your bathroom is quite different than the rest of the house. I think dark colors make me feel like I'm in a cave as they reduce light reflection. most bathrooms have pretty bright lights and often a larger ratio of window area. I put in a 3 bulb fixture and my girlfriend unscrews two of them
My take is that if that's all we have to worry about we are doing OK
