This is supposed to help you pick the best role colors, it also shows a preview for the light and dark themes of Discord.
The only thing different is the font, the one Discord uses is called "Whitney",
the main reason I dont use it is because it costs money, and its not cheap...
the second reason is because it's weird, some specific colors really bleed over into the background -_-

Its pretty self explanatory but anyway^^

• Click on the username to change it, both in the row will be changed.
  (That on isn't as obvious as the others...)
• Click to change the color...
• Click to copy the color to your clipboard.
  Format will be in hexadecimal aka "#FFFFFF".
• Click to duplicated the row.
• Click to delete the row. You can't delete the last one.
• Click (the big one... kinda hard to miss) to add a new row.
• Click at the top right to hide/show the instructions (the ones you are reading right now).

BTW this site remembers your changes if you want to reset use those buttons:

reset color palette reset user colors reset both

hide the instructions next time?
