Ordering question for small rip-rap

I wish to order “small rip-rap” in the following colors: 500 cactus berry winslow, 117 mauve (stone chips), 109 Cumbres “scenic rock” and 400 Southwest Chief Desert Plum rip-rap.  In you drop down menu, I don’t see “small rip-rap” listed.  Please advise what to order in each color listed.  Thanks.
