I can't really identify three of these four with the ones in The Chip Rack, unless my yellow is mustard. Anyway, at least two new colors. Haven't seen the original submission of colors to see if they might be faded or otherwise not reliable. TCR currently lists be-bi-bo-gy-gn-lbl-mu-pu-rd for N4160.

These chips are all unused and don't appear to be faded. I'd suggest peach, white, yellow, and red for the colors.
