Let’s get started!

Brief Overview of Slack

Before diving into their new logo, let’s introduce you to Slack. As one of the famous collaboration platform logos, Slack allows employees and managers to communicate and exchange files. 

Slack may be a simple and understandable word, but did you know that, in this case, it’s an acronym for “Searchable Log of All Conversations and Knowledge?” 

Founded by Stewart Butterfield, Eric Costello, Cal Henderson, and Serguei Mourachov in 2013, Slack was designed to revolutionize the way teams communicate and collaborate in this digital age. As they developed the product, these four founders recognized the importance of visuals for a strong brand identity that instantly captured their customers’ attention. 

The initial Slack logo was a simple hashtag (#) symbol representing the central idea of bringing people together around shared topics and discussions. However, as the platform became popular, the team invested in a more comprehensive approach and changed its logo.

Like this famous collaboration logo, it’s essential to consider your company’s values, mission, and target audience when designing your logo. Follow Slack’s strategy and keep these points in mind:

1. Simplicity and versatility: Slack’s logo is simple yet conveys a powerful message. Aim for a design that’s easily recognizable and versatile across different platforms.

2. Meaningful elements: Slack’s logo’s hashtag symbol symbolizes collaboration and communication. So consider incorporating elements and iconography representing your company’s unique identity.

3. Color choice: Slack’s multicolor palette represents diversity and inclusivity. Check out color psychology to choose the right colors that evoke the right emotions among your target audience.

4. Taglines: Have you chosen a business name for your brand yet? If so, consider adding slogans to reinforce your brand message and provide additional context to your logo. The best example of this is the Nike Swoosh and its “Just Do It” tagline. Check out our tagline logos here.

5. Typography: Last but not least, typography is equally essential for brand recognition. Choose fonts that complement your logo and reflect your brand’s personality well. Go with a sans-serif font if you want a clean and sleek font. However, there are thousands of typography trends that you may explore, so be sure to choose the best one that complements your overall design.

The Slack Logo: Before and After

Like the other famous logos, the Slack logo you know today is not the company’s first design. However, unlike popular symbols such as Twitter and one of the renowned motorcycle logosHarley Davidson, Slack has only two design variations: the first and the current logo

In this section, let’s learn more about Slack’s first-ever logo design and newest version.


Shortly before its launch in 2013, Slack introduced its first logo, which featured an octothorp, also known as the “hashtag” symbol. The octothorp-shaped logo was designed with a unique and distinctive appearance, setting it apart before Instagram and similar platforms existed.

The logo’s 11 colors and perfect 18-degree angle contributed to its eye-catching and memorable nature.

However, in 2019, Slack decided to rebrand and unveil a new logo. The motivation behind this change likely stemmed from a desire to evolve and better align the visual identity with the company’s growth and messaging. 

As companies expand and mature, they may undergo rebranding efforts to ensure their branding remains relevant, appealing, and consistent with their current values and objectives. 

Additionally, a new logo can signify a fresh chapter for the company and help maintain its competitive edge in a rapidly evolving market.


In 2019, Slack unveiled its new logo and gained positive reactions and comments from its users. But what’s wrong with the first logo, and why did they change it? You might ask.

The previous logo became increasingly complex and posed significant challenges for the company. Its intricate design made it susceptible to errors in angle and color, potentially leading to detrimental effects on its brand image.

Moreover, the logo needed compatibility with various backgrounds, risking clashes with the surrounding visuals. To tackle this problem, Slack adopted different symbols for multiple formats, including a unique logo for the app, as they needed a comprehensive branding strategy.

Slack Design Elements

In this section, let’s dissect two of Slack’s design elements: the symbol and colors. Check it out below.


The Slack symbol is an abstract representation of a speech bubble, cleverly crafted in the shape of the octothorp or the “hashtag” symbol (#). This symbol embodies the essence of Slack’s purpose: to facilitate communication, collaboration, and discussion among teams and individuals.

Using the octothorp as the base shape adds a modern touch to the symbol. It also refers to the platform’s initial logo, connecting to its early days and reflecting the company’s evolution.


The Slack logo is characterized by its vibrant and diverse color palette, significantly defining the brand’s personality and creating a visually engaging identity. It features a spectrum of colors arranged diagonally within the speech bubble-like symbol. The colors used include green, yellow, red, and blue variations.

According to color psychology, each color within the logo holds symbolic significance:

1. Green: Green represents growth, harmony, and balance, which signifies the development and progress of teams and individuals collaborating on the platform.

2. Yellow: Yellow shows positivity, energy, and optimism, reflecting the enthusiasm and creativity of effective communication and idea exchange within the Slack platform.

3. Red: Red exudes passion, determination, and urgency and symbolizes the drive for productivity and successful teamwork that Slack fosters.

4. Blue: Blue evokes trust, professionalism, and reliability. It embodies the secure and dependable environment that Slack provides for its users.
