Basic neutral colors like black, white and pearl match well with red. Deep purple hues and metallic hues like gold also look great with red.
Silver jewelry is flattering with red as well and can give a red outfit an elegant or modern look. Medium shades of red are most flattering with purple. If these are the two main colors of the outfit, accessories in black or gray can bring balance to the look. Yellow is striking against red. Accessories in this color can be worn with a red dress or top. Pink goes well with red and creates a monochromatic color scheme.
