Red is by far the most used colour on flags, appearing on 76% of all national flags.
There’s a good reason for that.
Red is a colour that has been used to communicate many important messages since the very first humans started making images on cave walls with materials like ochre.
And just think of all the different messages we communicate with the colour red. It means ‘danger,’ presumably because red is also the colour of freshly shed blood. It means ‘love,’ perhaps because we tend to flush when we experience feelings of excitement and affection. It means ‘anger,’ because we also flush when we are angry.
So it makes sense for red to feature on national flags, which are often used to garner feelings of solidarity and willingness to act at times of war (or football), sentiments of love and affection for the motherland, and the determination to stand up for our country when it is under attack.
