For our color-blind friends, a couple of themes people on our team here at Slack have found useful.
If you’ve never tried changing your sidebar colors before, or didn’t know it was possible… Surprise! It is! (And is a very useful thing to do, particularly if you’re on multiple teams.)
In your user preferences (the menu at bottom left, next to your avatar), simply go to Preferences > Sidebar themes, and choose the “Customize your sidebar colors” option under the default themes.
Then copy and paste the values below into the box.
Solanum: A sidebar theme for Protanopia and Deuteranopia (Green & Red deficiency)
#4F2F4C, #452842, #8C5888, #FFFFFF, #3E313C, #FFFFFF, #D0FF00, #889100
Brinjal: A sidebar theme for Tritanopia (Blue deficiency)
#4F2F4C, #452842, #8C5888, #FFFFFF, #3E313C, #FFFFFF, #00FFB7, #DE4C0D
(And if you’ve created any other helpful — or beautiful — sidebar themes, feel free to tweet them at @SlackHQ. We’d love to be able to share them.)
