That arguement is very opinion base with no hard evidence supporting it. Red is generally accepted by the people as a more attractive color in terms of getting their attention. Researches has shown that people dressing in Red gets more attention than those in blue. Go search up Red gets attention and look at the results
Blue's a better color because its a lot more soothing for the eyes, not to mention that red is always associated with violence and any type of alert of danger. Look at the Red card from sports. And that people like the color blue because its more manly
Going on from what you said in the previous arguement. ill have to disagree. The color red is used in alert and danger sign because Red is because our eyes tend to focus on brighter and a color most different from our surrounding. Take the fire truck for example. they're red and uses red light because they have to let make other drivers be aware of their presence on the road. Additionally stop light also work the same way. The flashing red can easily attract our attention to prevent us from walking into a street with cars still driving. But Define your definition of "better"
I define the word better as in stronger and liked by more people. You don't see any Red stickmen winning in a Blue vs Red animation do you? that's because people like Blue better and why they always make Blue win
