EVER wonder why Starbucks baristas will wear different colored aprons?

Well, it's not entirely random. From green and black to red and orange, each apron has its assigned meaning.

The green apron, which is the chain's signature color, is the one you will likely see most employees wearing.

It can be dressed up based on the employee's accomplishments.

For instance, if someone was in the military they could get special patches on their apron, like an American flag, according to Delish.

If you happen to see a mortarboard embroidered apron, you can bet that employee is a graduate of the Starbucks College Achievement Plan.

Introduced in the early 90s, the black apron is reserved for more seasoned employees. These are the people referred to as 'Coffee Masters,' who have expertise in Starbucks coffee.

To become a master of coffee, they have to be selected for the program and be able to answer all coffee-related queries on the following: Taste, roast, acidity, and body profiles, as well as growing methods, varietals, food pairings, how temperature affects taste, and more.

The red aprons were released for the holiday season, while orange aprons are used to celebrate Kings Day in the Netherlands.

Purple aprons, on the other hand, are for barista champions, and there are only 26 chosen every year, according to Taste of Home.

Just like you may not have noticed the different Starbucks apron colors, another thing that might have gone over your head is how the Starbucks logo has changed over the years.

When the first Starbucks store opened in 1971, the logo looked quite different from today.

The first logo featured the same long-haired mermaid or 'siren' that we're all used to.

Back then though, she had a bare chest and large tail on display.

Instead of its famous green shade, the first logo was also brown and had the brand's full name, 'Starbucks Coffee, Tea, and Spices' on display.

In 1987, Starbucks merged with the expresso brand Il Giornale which inspired a new logo.

This is when green became the company's signature color, the siren began to look more modern, and their name was shortened to Starbucks Coffee.

The siren became more pronounced in the 1992 logo, but the Starbucks name was still a part of it.

This is the logo the brand is most known for, and it would serve as the Starbucks symbol for almost 20 years.
