Red is the ultimate attention-grabber. It's like a loud, fiery bell that screams "Hey, look at me! I'm red and I'm here to stay!"
Yellow is the colour of sunshine, happiness, and also the colour of warning signs that say "Caution: Do not enter, because you're probably going to slip on a banana peel"
Blue is the colour of the sky, the sea, and the feeling you get when you've eaten too much cheese and you can't get out of the house because you're stuck on the couch with a wheel of cheddar
