I don't think I dislike a specific colour all the time.
Even though grey used to be my least favourite colour, when I was younger.
I remember even writing in a book or something, when I was younger "Favourite colour: all of them except grey"
Sometimes I dislike the colour red, because I find it "scary-looking" sometimes.
Other times I dislike the colour blue, especially in the month of April where some people "light up blue".
When it comes to clothes, I sometimes dislike only wearing grey, black and blue.
Or when I wear an outfit that is black, white and grey, looking like someone attending a funeral in a silent movie.
Even though there are times when I want to look a bit fancy or edgy by wearing black.
I don't like wearing yellow clothes, when it is "wasp season"
