If you're using the mobile Slack app, whether it's for work, school, or gaming, you know that the background color in discussions for channels, threads, and direct messages is white and most of the text is black. Unlike the sidebar, there is no way to customize the colors displayed here, but you have another option: dark mode.
Slack comes in two different color themes: light and dark. Light is the theme you are used to, with white background and black text. Dark is the newer, higher contrast color theme that reverses these colors for an almost black dark gray background with mid-gray elements and light gray text. The dark mode, sometimes referred to as the night mode, has several advantages over the light, which I'll talk about later.
Dark mode was released in March 201
Using Slack's Dark Mode
If you've selected the correct Slack version, tap the vertical ellipses (•••) in the top right corner and choose Settings. If you're on an iPhone, tap the switch next to "Dark Mode." It would be in the third section right after "Advanced".
On an Android phone, it would be in General but it's not a toggle. Just tap on "Dark Mode: Darker Mode is Off" and a popup window may warn you that a reboot is required. Tap "Next" if that's the case, and if the app is available again, you have the darker theme.
Changes are displayed immediately after activating the "Dark Mode". You see the super dark and medium gray backgrounds in the app, the text is light gray and the links are still blue.
Pictures are not like in some reverse modes so this is the real deal.
First, it's more eye-friendly when you read and write, especially in low light conditions. When you're in bed or getting up late, your dazzling whiteness will not affect your vision. Second, it just looks cool, and it's another option besides the default, and customizations are always welcome. Third, the battery consumption of OLED screens can be lowered.
When true blacks are used in black mode, the pixels for these blacks are disabled and turned back on when scrolling. Sounds good, but this could cause an unintentional fade, so that many dark modes increase the color a bit to a dark gray, which improves the life of the OLED screens.
Something that is not affected by Slack's new dark mode is the sidebar partition. The backgrounds and font colors of the sidebar are what you set them for, regardless of whether you have selected a standard sidebar theme, such as "eggplant" (see below) or custom colors.
If you want to get the dark theme in the sidebar Well, you need to design a custom theme with black or dark gray colors as the background and light gray text. Keep in mind, however, that changing the sidebar theme, unlike the Dark mode, changes the theme on all Slack platforms – Mobile Apps, Website, and Desktop Apps mode on the phone
