What the sunrise looked like on an overcast December day. 

Many might not notice this kind of sunrise. Even when they’re in the situation of the first photo they don’t see the red color, they only see what they always see. 
If you really note the way your surroundings change color through the day and types of skies – you will be able to see this kind of sunrise. 

Just look around and don’t take the colors for granted. They are (slightly) different every time you look outside ;-)
