For example, I constantly (sic!) Check the subway cars and public transport tickets for “happy”, i.e. the coincidence of the amounts of the first and last three digits. I think many people do the same thing, some even counted how many (lucky numbers) of them all, but what exactly nobody did was this
Huge gradient 55252x1px Lucky numbers are exactly 55252 (0-100000), each pixel of a huge gradient is a lucky number as a color. For example 239815 it is R23 G98 B15. The python script helped me in this. And this is ↓ happy color, which in itself is not a happy number :)
