Nooooooooooooooooooooooooo
It never ceases to amaze me that Thai's can build some stunning Temples, beautifull complementary colours etc
but when it comes to choosing paints and tiles for the average home ...
1/
Develop a colour/texture palette.
2/
Start with the item of which there are the least choices. Usually the Curtains/drapes or the floor coverings.
3/ Leave the paint till last ... there are a gazillion paint colours.
Start with this ...

Greens ...

Remember, colours will darken when used in large areas. What it looks like on a colour chart will look slightly darker when painted on a wall.
Grab a tile you like, some fabric and then match a wall colour.
IMHO, those multi coloured/patterned tiles so popular on Thai Flooring look
Stuff like this ...

Back to your wife. Was she born on a Wednesday?
'Green' is the Wednesday colour and some/many Thais believe that is their house colour matches their birth colour,
they will lead a better/richer life.*
Assuming you don't wish for a green house, compromise on this.
Allow her to choose the colour for the Spirit House or
spirit room ... that's more important to Thai's (generally).
All, of course IMHO
