Playing cards are two colored, when i play i prefer them just like they are

Playing cards were born from the Tarot cards, and they also have some meaning besides the games.
I respect that.
p.s
When you play 4 colored you are probably 4 eyed one 👓 , or probably you are playing UNO...
I used to always use the two color deck because I was old fashions, LOL till I realized sometimes I would miss read my cards. So for the last year or two I've been using the four color deck definitely is easier once you get used to it , just might save you some money also.
I use just the two color deck.
If you play live, the deck is the same, but yes, online if you play on 4-8-16-etc tables the 4 color deck is better
I never made a mistake because of a 2 color deck (flush)
I played 2 colors for a long time and thought that 4 colors looked ugly, but once I saw a flush on the board without a flush and decided to use 4 colors. Now I think the 4 colors look pretty good.
