If you're looking to coordinate colors, keep this in mind:  All black, pink, and red gloves, Banjees wrist wallets and Earbags match each other.  But for Hotcollars neck warmers only the black is an exact match for the gloves and wrist wallets.  If you're looking for a complete matching ensemble which includes the Hotcollars neck warmers, black is your only option.

Here is a breakdown by color:
Black: All black accessories and Earbags match.
Camel: The gloves and Banjees wrist wallets match.  The camel Earbags are nearly an exact match with the gloves and wrist wallets (most people consider them a match), but the Earbags are in fact a slightly lighter shade of camel.  The camel Hotcollars neck warmers are a lighter shade of camel (more like beige or bone) than the other camel items, and are not an exact match.
Blue: No exact matches. Each product line is a different shade of blue.
Red:  The gloves, Banjees wrist wallets and Earbags match. Hotcollars do not match.
Pink: The gloves, Banjees wrist wallets and Earbags match.
