🎯 Design Principles

1. Color Coding

Action Colors:
  🟢 Green  → Start/Play (confidence, action)
  🟠 Orange → Pause (caution, transition)
  🔴 Red    → Stop (danger, critical)
  🟣 Purple → Special (schedule, control, exit)
  🔵 Blue   → Primary (information, default)
  🔵 Cyan   → Refresh (reset, update)

2. Visual Hierarchy

Primary Elements:
  • Large, bright colored buttons
  • Easy to locate
  • Main actions

Secondary Elements:
  • Standard size buttons
  • Secondary actions
  • Supporting controls

Tertiary Elements:
  • Small, subtle elements
  • Status indicators
  • Text labels

3. User Feedback

On Hover:
  • Button color darkens
  • Cursor changes to pointer
  • Visual indication of interactivity

On Click:
  • Button appears pressed
  • Status updates immediately
  • Action confirmed

On Disable:
  • Button grayed out
  • Cursor shows unavailable
  • User understands not clickable
