I prepared a mood board before hand, as you can see the blue in the image are bright blue or you can call it battle blue, Vogue named it. Unfortunately I don't have any that blue, so it ended up with a black window. I was not happy with it, but I didn't have time change another theme.
On my way home, I went pass a bathroom shop and saw these glasses, I decided that my windows's colours were too cold, it should be mixed with some warm colours, even just a tiny bit. So next day , I went back to the shop, and added some pink colours in the windows, like added a few pink flowers in the whites. But I was too busy to have time to take photos, that's shame. But it really made big difference to the whole window, colour is such a magical thing.
