Garage door learn button colors explained

For many Chamberlain, LiftMaster and Craftsman residential openers, the learn-button color is a quick way to identify the receiver generation when the model number is hard to read. It is a fallback identifier, not a substitute for brand or model verification.

Identifier	Radio family	Verified opener records	Current accessory records
White learn button	Security+ 3.0	11	12
Yellow learn button	Security+ 2.0	32	15
Purple or brown learn button	Security+ 315 MHz	0	15
Red or orange learn button	Security+ 390 MHz	0	15
Green learn button	Billion Code 390 MHz	0	9

What each color means

White learn button

Security+ 3.0. Current Chamberlain-family generation. Use accessories that explicitly list white-button / Security+ 3.0 compatibility; Security+ 2.0-only accessories are not interchangeable.

Yellow learn button

Security+ 2.0. Common Chamberlain-family rolling-code generation introduced before the current white-button Security+ 3.0 family. Many current multi-generation remotes still support it.

Purple or brown learn button

Security+ 315 MHz. Legacy Chamberlain-family Security+ 315 MHz generation.

Red or orange learn button

Security+ 390 MHz. Legacy Chamberlain-family Security+ 390 MHz generation.

Green learn button

Billion Code 390 MHz. Older Chamberlain-family billion-code generation. Confirm accessory coverage before purchase.

Why the same accessory can appear under several colors

Modern multi-generation remotes can contain support for several historical Chamberlain-family protocols. That does not merge those opener generations into one protocol; it means the accessory implements more than one. Check its published compatibility list to make sure your exact color/generation is present.

Common color-reading mistakes

Using the color of a wall control instead of the opener-head learn/program button.
Calling every dark button “black.” Manufacturer compatibility tools often group purple/brown and red/orange as family labels.
Ignoring a receiver-board replacement. The current board can change the relevant color.
Applying the chart to Genie, Linear or another brand where the same visual cue has a different meaning.

When color is not enough

If the opener brand is uncertain, the learn button has been replaced, or the accessory manufacturer lists a model-specific exception, stop at the color result and verify the exact opener or receiver documentation. Use the interactive color finder to see only accessories whose manufacturer specifications explicitly include the selected generation.
