Which of the following is a gang-related identifier?

The identification of specific colors as a gang-related identifier is based on the practice of gangs adopting distinct color schemes to signify membership and affiliation. These colors often hold significant meaning within the gang culture, representing unity, loyalty, and sometimes even territorial claims. The use of colors can be visibly displayed through clothing, accessories, and graffiti, making it a recognizable symbol among members and the community.

In contrast, while other options may involve organization or affiliation, they do not specifically denote gang membership. Use of formal contracts typically relates to legal agreements, which are not characteristic of gang culture. Organized sports teams may have their own colors and uniforms but function under different social and organizational rules, focusing on athletic competition rather than gang dynamics. Assessment tests are merely evaluative tools and have no relation to the identifiers associated with gang membership. Thus, specific colors stand out as a clear marker of gang affiliation.
