They updated their logo to make it look much newer and updated than the last boring and bland.
The colors chosen for Netflix is usually red, white, and black. These colors represent a bold business who have things to offer for people.
Netflix changed their logo many times. I think the change was for the better because it is a bold change in which colors are primary in the logo. The logo change was just an update to the old one to change things up.
Burger King kept their colors pretty much the same. They had red because its a appetizing color, while yellow is usually positive and a happy color.
Burger King only had one major change at first. Then it just got updated time by time to look more professional and with help with newer technology and editing. The last biggest change was putting a blue ring around it.
