question on window channel clips

i ordered the window channel clips from year one and they gave me two different ones green ones and brown ones i dont under stand how the green ones work the brown ones work but theres not enough so idk no if your saposed do every other one brown or what its prolly a stupid question but if ne one can help plz do travis

Not really sure, but my first thought would be that one color is for one side and one color for the other. Good luck
