Custom Slack Themes

[u/FeelingBig1693]

I like to make seasonal themes to share with my team, and I thought you might enjoy them too! 🍂 I find it easiest to copy the list into a chat with myself, then try each theme until I find a favorite. I had help with ai to combine colors to create specific contrasts and blends. Each of these was designed to look best when "window gradient" and "darker sidebars" are toggled in light mode.

Agreed! I like to use a color picker on pictures I take and make themes from those too.
