Warm and cool LIGHTING??

I noticed that the cool toned lighting in one room of my house flatters me a lot. Even if I’m wearing my worst colours I’ll still look somewhat okay. It’s what made me so confused on what season I was, because every time I looked in the mirror I would look good no matter the colour. And with warm lighting, I don’t look as good. I also noticed that I look better when it’s cloudy outside. I think everyone looks good in sunlight but I think I look a bit better when it’s overcast. Has anyone noticed this with their undertone or am I just going crazy???
