Commonly seen popular school colors and combinations include:
* Blue and Gold: This is arguably one of the *most* popular pairings worldwide.
* Red and White: Another extremely common and widely used combination.
* Blue and White: A very popular and classic choice.
* Green and White: Often seen, especially for schools with a nature or agricultural focus.
* Purple and Gold: Less common than the above, but still relatively frequent.
It's important to note that many schools also use variations and shades within these color palettes. For example, a school might use navy blue and gold, or royal blue and gold, instead of simply "blue and gold."
The reason for the popularity of these colours is likely a combination of factors: they are considered pleasing to the eye, they are readily available and affordable, and they possess symbolic meanings (blue often represents loyalty or knowledge, red represents energy or courage, gold represents achievement, etc.).
