货色 literally means 'type of goods', but it has two distinct tones. In neutral contexts, it means 'merchandise' or 'stuff' (e.g. 这家店的货色不错). However, it often carries a derogatory leaning, implying cheap or worthless goods — equivalent to 'junk' or 'trash' (e.g. 这些货色没人要). The connotation depends heavily on context and modifiers; alone it can be neutral or negative.
