2. Squint your eyes
3. If you can still read it → Good contrast ✅
4. If text disappears → Poor contrast ❌

### The Distance Test:
1. Sit back 3-4 feet from monitor
2. Can you still read all text? → Good ✅
3. Text blends with background? → Poor ❌

### The Grayscale Test:
1. Take screenshot
2. Convert to grayscale
3. Check if all elements still distinguishable
4. Lost elements → Relying too much on color alone
