From left to right: "see through olive", dark mustard, medium mustard, light mustard, chartreuse mustard ponies, all Mold 1. The difference between see through olive & dark mustard seems to be one you have to see in person...if you have good color perception after seeing them together in person you'll know what I mean. The dark mustard definitely has more amber tone.

Sorry for the photo quality. I'm still learning to use my Nikon D-3100 DSLR.
