show a side on picture so that we can see the swelling better.
As for the color, that is probably just a result of the particular strain of b. linens that have colonized your rind (this is good, you want those little buggers) Some will be yellow, some will be golden brown, some will be red, and some are orange. Deep orange can also be the fault of over drying, but since you say it is sticky that makes me say it is orange b. linens. These will make the cheese kind of sticky, but later on they dry out.
