In honor of the first day of spring, Google is celebrating with a new, colorful Doodle. On its homepage, the search engine replaced its official logo with a Doodle designed by Marimekko, the Finnish textile company known for its bright prints.

The Doodle features blue and pink flowers for the first G and O of the search engine’s logo. A yellow and black bird replaces the second O, while blue butterflies represent the second G. A green truck with green balls stand in for the L, while a pink zebra is included for the E.

Eight Finnish designers worked on the Doodle, including Maija Isola, Kristina Isola, Erja Hirvi, Maija Louekari, Aino-Maija Metsola, Teresa Moorhouse, Jenni Touminen and Katsuji Wakisaka. The designers were approached to create the Doodle by Google’s Vice President, Marissa Mayer, visited Marimekko’s textile printing factory in Helsinki.

The Doodle marks the vernal equinox, which signals the start of spring. An equinox is one of two times during the year when the length of day and night are just about equal. The March equinox signals the end of winter and the beginning of spring in the northern hemisphere. Astronomers have said the equinox mark the moment when the sun arrives at one of two intersection points of the ecliptic and the celestial equator.
