Here's a review for some yellow/gold lenses!
As you can see below, I have dark brown eyes and the color shows up very well. =)
These are 'Dolly Eye Brown' lenses from Colorcon Koumi: http://akirakozue.tumblr.com/
Even though it says 'brown' they are very much a golden color. The lenses are yellow, though when I put them over my dark brown eyes, it softens the sharpness of the yellow and gives it a very warm, more natural gold.
I give the comfort level about an 8/10 but that's simply because I have chronically dry eyes, so no contacts are very comfortable for me XD Compared to other lenses, however, they are at the top of the list for most comfortable.
These are all indoor pictures with no flash. They are even more vibrant outside!
