Do & don’t

What makes it Plain
  • Bright, saturated green used for headline text and the primary button
  • Monospace-style uppercase button labels, like a developer tool
  • Light green tinted surfaces instead of plain grey
Do
  • Use the bright green as the dominant brand colour on headlines and buttons
  • Use uppercase, slightly technical-looking button labels
  • Use pale green tints for secondary surfaces
Don’t
  • Don't tone down the green to a muted pastel
  • Don't use soft lowercase button labels only
  • Don't use cold grey surfaces

For AltLeads: Borrow the bold single bright-green brand colour to make the product feel modern and technical rather than corporate.
