How To Make Slack Dark

As an individual who devotes a considerable amount of time using Slack, I recognize the significance of having an aesthetically pleasing interface. One way to personalize Slack and enhance its usability for your vision is by activating the dark mode. This guide will take you through the process of enabling the dark mode on Slack and also provide my personal perspectives on why I favor this setting.

Why Dark Mode?

Before we dive into the steps, let me briefly explain why I find dark mode so appealing. The dark mode, also known as the night mode or dark theme, swaps the traditional light background with a darker one. This switch not only provides a sleek and modern look to applications like Slack but also reduces eye strain, especially during late-night work sessions.

Now, let’s get started with enabling the dark mode on Slack.

Step 1: Accessing Preferences

To begin, open Slack on your desktop or web browser and log in to your account. Once you’re logged in, click on your profile picture or avatar located on the top left corner of the screen. A dropdown menu will appear; scroll down and click on “Preferences.”

Step 2: Selecting Themes

In the Preferences menu, you’ll find various options to customize your Slack experience. Look for the “Themes” tab on the left-hand side and click on it. This is where you can change Slack’s appearance and choose the dark mode option.

Step 3: Enabling Dark Mode

Within the Themes tab, you’ll see different theme options, including Light, Dark, System Default, and other custom themes. To enable the dark mode, simply click on the “Dark” option. Slack will instantly switch to dark mode, transforming the background to a darker color.

Take a moment to appreciate the new look. Personally, I find the dark mode much easier on the eyes, especially when working in low-light environments or during late-night brainstorming sessions.

Step 4: Customizing Accent Colors (optional)

If you’re feeling adventurous and want to add a personal touch, Slack also allows you to customize accent colors. Under the “Themes” tab, you’ll find an option to change the accent color. Click on it and select your preferred color from the palette. This feature enables you to make Slack truly unique and align it with your personal style.


Enabling dark mode on Slack is a simple yet effective way to enhance your user experience while reducing eye strain. The sleek and modern look, along with the ability to customize accent colors, makes the dark mode a great choice for those seeking a personalized touch. So, go ahead and make Slack dark, and enjoy a visually appealing workspace!
