It turns out that these onions are actually called red onions, despite their outer appearance. So why are they called red onions if they are purple on the outside?

The answer has to do with the way that these onions are grown. Red onions get their name from the fact that they are grown in a way that allows them to absorb more sunlight than other types of onions. This extra exposure to sunlight causes the outer layer of the onion to develop a reddish hue.

Why are Purple Onions Called Red Onions

Purple onions are actually a type of red onion. They get their color from a pigment called anthocyanin, which is also found in red wine and blueberries. Anthocyanin is an antioxidant that has been linked to several health benefits, including reduced inflammation and improved heart health.

When They are Young, They Have a Reddish Color

As they age, the salmon gradually turns to a darker red, eventually changing to almost black. Salmon are one of the most popular fish in the world and are known for their delicate flavor and pinkish-orange flesh. Salmon get their pink color from carotenoids in their diet which are also responsible for giving other animals and plants like carrots, tomatoes, and flamingos their hue.

The amount of carotenoids in a salmon’s diet dictates how pink its flesh will be – wild salmon that consume lots of shrimp and krill tend to be more colorful than those that eat mostly smaller fish. Salmon usually have a lifespan of around 4-5 years but can live up to 8 years in captivity. During this time, they slowly change color from reddish when young to dark red or even black as they age.

This is due to changes in pigment cells called chromatophores – as salmon grow older, these cells produce less red pigment (astaxanthin) causing the fish to appear darker overall. While the exact reason for this change isn’t fully understood, it’s thought that it may help camouflage them from predators or make them more attractive to mates later in life.

As They Mature, They Turn Purple

As they mature, eggplants turn purple. Eggplant, or aubergine, is a species in the nightshade family. The fruit is widely used in Mediterranean and Asian cuisine.

Though technically a berry, it is often considered a vegetable. Eggplants are low in calories and a good source of fiber and vitamins. They also contain phytonutrients that have been linked to health benefits such as reduced inflammation and improved heart health.
