In The Walking Dead, the green and white arrows (specifically crossbow bolts) were gifted to Daryl Dixon by Michonne.

In the Season 3 episode "Clear," Rick, Carl, and Michonne encounter Morgan Jones, who has a massive cache of weapons. Michonne finds a new, more advanced compound crossbow—the Stryker StrykeZone 380—and brings it back for Daryl. This new crossbow came with high-quality, commercially produced bolts that featured distinctive green and white fletching (the "feathers" at the end), replacing the orange and yellow ones he had previously used.

Key Facts About Daryl's Arrows

Source: While Daryl is often seen crafting his own makeshift arrows from wood and scavenged materials, the green and white bolts were professional-grade factory equipment found in Morgan’s armory.

Symbolism: Fans often associate the white fletching with the character Beth Greene, as she is seen handling them during their time together in Season 4, leading some to refer to them as "Beth arrows".
