Declan Rice says Arsenal's No More Red campaign, which aims to combat youth knife crime in London, can have a "massive" impact on young people.
Arsenal will wear a white kit for Sunday's FA Cup third-round tie against Liverpool to highlight the initiative.
The campaign wants to provide more safe spaces so young people can live without fear in their communities.
"You can meet new people, you can meet people who you can talk to and become friends for life," Rice told BBC Sport.
The one-off kit will not go on sale, but will instead be awarded to individuals who are making a positive difference in the community.
