Slack: Brand overview

Founded:August 2013
Founder:Slack Technologies
United States
Slack is positioned as an excellent alternative to Skype and even as its “killer” because it alone can replace corporate messengers and e-mail. The instant messaging system allows you to bring the whole team together to discuss working moments. For each topic, you can create your channel, and for one-on-one communication – go to personal correspondence. Another plus is that the program has versions for different operating systems, including the desktop one for Microsoft Windows.

Meaning and History

Slack Logo History

One of the best business applications might not have emerged if Tiny Spec hadn’t created Glitch. In the course of its development, a messaging service was invented, which in the future served as the basis for Slack.

The corporate messenger was launched in August 2013. It used a logo with a colorful hashtag rotated 18 degrees. Users got used to the company’s corporate identity, so they were outraged when it changed the octothorpe’s design. People looked at the new symbol for the four ducks, the swastika, and the Google Photos app icon.

What is Slack?

This is the name of the American company and its flagship product – the messenger developed by Slack Technologies in conjunction with Salesforce. The client is designed for instant messaging between employees within the same enterprise.

2013 – 2019

Slack Logo 2013-2019

The first emblem appeared even before Slack itself. It contained two elements, one of which was a pound sign. The hashtag consisted of four rounded strokes: red, blue, green, and orange. Where the stripes overlapped, complementary colors were used to make the image appear semi-transparent. Despite being two-dimensional, it added depth to it.

The messenger’s name was written to the right of the octothorpe and balanced the color palette with a restrained gray color. The designers chose the Larsseit ExtraBold font, making all the letters lowercase. Thanks to the lack of serifs, the word was easy to read even at a reduced scale.

Slack Logo 2019-present

Slack owners had several complaints about the first logo:

  1. It didn’t look good on a bright background due to its complex palette, which contained 11 colors.
  2. The lattice sign lost its appeal if it was placed at the wrong angle.
  3. The company had to use several versions of the logo that had nothing in common.

For example, the app icon was missing a hashtag.

To make visual identity more consistent, Slack executives turned to design agency Pentagram for help. Responsible for the image change was Michael Bierut, creator of the famous Hillary Clinton and Mastercard logos. After a long creative search, experimenting with different forms, he decided to keep the original octothorpe but change its style. As a result, the sign became more abstract.

The new logo embodies the original spirit, although it uses far fewer colors and lacks the usual transparency effect. The disappearance of overlapping elements makes the image flat, but designers don’t see this as a significant issue. The main thing is that now it can be placed on any background, not just white. The caption has also changed: the name of the program has become black. The letters have lost their rounded corners, although, in general terms, the font is similar to the previous one.

Font and Colors

Slack Emblem

The first Slack graphic was 100% in line with the concept of a corporate messenger. It was associated with the hashtag that was the organizing element of the application, stood before the channels’ names, and quickly found messages.

After the redesign, the iconic grille mark disappeared. Its place was taken by an abstract multicomponent composition consisting of four rectangles with rounded sides and four teardrop-shaped figures.

Each circle symbolizes a cloud of text – the so-called callout, which is used to transmit speech. This refers to the main function of the application, a hint of communication and interaction between users. Moreover, the new emblem is designed to be freely divided into parts, reduced or enlarged.

The bold sans serif that Slack uses is from the Larsseit family. For the redesigned logo, the designers slightly changed the lettering, adapting them to the stylized octothorpe.

The simplified palette includes four colors instead of eleven: red (# E01E5A), green (# 2EB67D), yellow (# ECB22E), and blue (# 36C5F0). The shades have been improved to look great on screen. Also, there are two more colors on the emblem: black for the inscription and white for the background.


What is the Slack icon?

The Slack icon is important to the brand’s desktop and mobile app identity. This icon helps members identify their workspace or Enterprise Grid organization. Users can upload a custom icon to make their workspace unique and recognizable.

Go to the desktop app to update the Free, Pro, Business+, and Enterprise Grid plan icons. Click on your workspace name in the sidebar to access settings. Upload an image to serve as your workspace icon.

The icon personalizes the workspace and helps members quickly find and differentiate between multiple workspaces. This feature enhances the user experience by providing a visual cue that aligns with the workspace’s branding.

What font is the Slack logo?

The logo uses Hellix Bold font and features an octothorpe, a hashtag. This combination creates a unique and recognizable look for the brand.

Hellix Bold makes the logo modern and professional, matching Slack’s image as a top communication platform. The octothorpe symbolizes connectivity and communication, which are key aspects of the brand.

Using Hellix Bold makes the logo clear and impactful, helping it stand out across different platforms and devices. This font choice ensures a strong and consistent brand presence, making it easily identifiable to users.

Why did Slack change its logo?

The brand changed its logo because the old one had major design flaws. The previous logo looked bad on any background that wasn’t white, making it hard to use in different situations.

Another issue was the multi-colored hashtag. When rotated at any angle other than 18 degrees, it didn’t look right and caused problems for the development team.

To fix these issues, the brand introduced a new logo. The new design is more adaptable and looks better on different backgrounds, making it more practical and user-friendly. The new logo is simpler, more consistent, and easier to recognize.

Is Slack a trademark?

Yes, the brand is a trademark owned by Slack Technologies, Inc. This trademark protects the brand’s name and logo, ensuring that only Slack Technologies, Inc. can use them for their products and services. This legal protection helps maintain the brand’s identity and reputation.

Trademark protection prevents others from using the name or logo in a way that might confuse consumers or harm the brand’s image. If another company tried to use a similar name or logo, it could mislead people into thinking they are using products or services that might not meet the same standards.

Having a registered trademark supports marketing and branding efforts. It assures customers they use authentic products, fostering trust and loyalty. It provides legal action if any entity tries to infringe on the brand’s identity. This helps safeguard the quality and integrity of the brand, ensuring it remains distinct and recognizable in the market.

What is the Slack logo?

The logo consists of four rounded rectangles arranged in a turntable shape, with four drops in between. These elements are colored in blue, green, red, and orange pairs. Next to this design, the word “slack” is written in black, creating a clear contrast. This combination of shapes and colors makes the logo recognizable and visually appealing.

When did the Slack logo change?

Slack’s logo was redesigned in January 2019. The old logo had issues with visibility on different backgrounds and problems with the multi-colored hashtag. It only worked well on a white background, limiting its versatility.

The new logo features four rounded rectangles arranged in a turntable shape, with four drops in between. These elements are colored in blue, green, red, and orange pairs. The word “slack” is written in black next to this design, creating a clean contrast. This new design is more adaptable and consistent, making it easier to use across different platforms.
