Warmth: Blue Light Filter

Warmth is a small menu-bar utility that makes your screen warmer, on your terms.

Click the sun in your menu bar, switch Warmth on, and turn the dial from 0 to 100%. That’s it.

Warmth remembers your setting and keeps it right where you left it. No account. No setup. No tutorial.

ONE SWITCH. ONE DIAL.

• Turn Warmth on or off instantly • Adjust the dial by dragging, using the arrow keys, or with VoiceOver • Your setting stays saved across restarts and sleep • Turn it off, and your Mac’s normal colors return immediately
