"That's what we're proposing to the FDP," party co-chair Annalena Baerbock said in Berlin on Wednesday.
Baerbock said Germany faced major challenges that had to be tackled quickly, adding that the Greens were convinced that "this country cannot afford a long hangover."
Co-chair Robert Habeck said previous days of discussion had shown "that this is where the greatest overlaps are conceivable."
This was particularly true with regard to social policy, he said. However, the outcome of exploratory talks between the FDP and SPD — who may struggle to find common ground on economic policy — would also be a factor in any three-way deal.
After Germany's general election last month, the Greens and the FDP had talks first with each other and then separately with the SPD and with the conservative CDU/CSU union to explore possible lines of compromise.
"The cookie is far from eaten," said Habeck. "Many things still have to be discussed," he said, adding that the development did not mean the outright rejection of any coalition with the FDP and CDU/CSU.
A tie-up between the SPD, Greens and FDP would be a first in Germany. The mix has been dubbed a "traffic light" coalition after the parties' respective red, green and yellow colors.
Germany's colorful coalition shorthand
Foreign flags and even traffic lights are used to describe the various coalitions that emerge in German elections. Coalitions are common under Germany's proportional representation system.

Black-red coalition
The Conservatives black combined with the traditional red of the political left is the color code when the Christian Democrats govern in a "grand coalition" with the Social Democrats. This combination of Germany's two "big tent" parties, was in power first from 1966-69 and most recently for eight years until 2021, led by then-Chancellor Angela Merkel.

Black and Green
The conservative Christian Democratic Union (CDU) has teamed up with the ecologist Greens in several German states cooperating smoothly at the regional level. On the national level the two parties see eye to eye especially on strong support for Ukraine. They disagree on nuclear and renewable energy, and many conservatives despise the Greens for their multicultural and "woke" positions.

Black, Red, Green — like Kenya's flag
The center-right CDU/CSU could also team up with the Greens and the center-left SPD. This three-way coalition would be an option for a comfortable majority. It has been tested on a regional level: The eastern German state of Saxony was governed by such a coalition until 2024.

The Germany coalition — Black, Red and Yellow
The neoliberal FDP has been a junior coalition partner to both the center-right CDU/CSU and the center-left SPD. A three-way coalition was forged on the state level, for example in the eastern German state of Saxony-Anhalt. While this combination was touted as a possibility ahead of the 2025 vote, the FDP failed to get into parliament, ruling it out from any coalition building.

'Traffic light' coalition — Red, Yellow, Green
From 2021-2025 Germany was governed by a center-left coalition of Social Democrats (SPD), ecologist Greens, and free-market-oriented neoliberal Free Democrats (FDP), whose color is yellow. The government known as "Ampel" (traffic light) in Germany, started out as a self-declared "Fortschrittskoalition" (progress coalition) but got mired in infighting and became the least popular government ever.

'Jamaica' option — black, yellow and green
A three-way combination of Christian Democrats (CDU), the Greens and the neoliberal Free Democrats (FDP), has been tested at a regional level. But the FDP and Greens described their positions as irreconcilable following the collapse of the center-left government in November 2024. With the FDP's defeat in the 2025 election it will not be an option on the national level for the foreseeable future

Black and Orange
Since 2018 Bavaria's Christian Social Union (CSU) has been governing with the Free Voters (FV), whose color is Orange. The FV is a grass-roots populist and far-right-leaning party and is led by its controversial chairman Hubert Aiwanger. Strong in rural areas of southern and eastern Germany, the Freie Wähler is seeking a larger role at the national level and currently has three MEPs.

Blackberry Coalition
CDU (black), SPD (red) and BSW (violet). The new Sahra Wagenknecht Alliance's (BSW) color violet, seems fitting as it combines socialist, far-left (red) with populist right wing (blue) ideas in its platform. Although the party was only founded in 2024, it did so well in the eastern German states that it entered a coalition government with the SPD and CDU in the state of Thuringia.

Any combination of the Greens and FDP with the conservatives would be dubbed a Jamaica coalition, based on the party colors being the same as those that comprise the Caribbean island’s flag.
