It depends on personal preferences, I have also seen a lot of such collocations, and I think they are not bad, many of them are used to make aluminum alloy doors and windows.
It can be paired with pale yellow, light green curtains. You can take a look at the "Qijia" gallery, where there are many classic cases of similar decoration, I hope it will inspire you.
Gray curtains, mainly depending on the style...
The milky white with yellow curtains in the living room is beautiful and warm!
Curtains in cream white or pale yellow to match the colour of the walls and floors or dark brown curtains to match the colour of the sofa. (Personally, I think the dark coffee curtain is more upscale, and the dark coffee curtain is thicker, and a layer of milky white yarn with dark lines is installed underneath).
It is good with light coffee, and it can also be matched with light brown yellow, which is similar to your milky white floor.
