What would you like to do?
terminal theme for slack

Night mode for Slack Web


Installing a theme

You'll want to add this theme color to slack as well: #000000,#000000,#006600,#00ff00,#00ff00,#00ff00,#ff0000,#ff0000 which I got from this site here:

Instructions on how to add or customize slack themes can be found here

Adding the custom CSS above:

You'll need a chrome extension which allows you to write and persist custom CSS for a given website. I'm using stylebot for this. You can hit the Edit CSS button when you're on the web version of the slack room you want to change and paste in the CSS below.

body.light_theme, #footer_msgs, div.c-message.c-message--light.c-message--hover, div.channel_header, .c-scrollbar__hider:before, #search_terms {
background: #000;
span.c-message__body, .c-message--light .c-message__sender .c-message__sender_link {
color: #00FF00;
a, a:link, a:visited {
color: #006600;
pre.special_formatting {
background: #222;
color: #06b406;
.c-message_list__day_divider__label__pill {
background: #666;
#col_messages, div.channel_header {
box-shadow: inset 1px 0 0 0 #222;
.c-scrollbar__hider:before {
border-bottom: 1px solid #222;
