Can basal cell cancer be the same color as skin?

Unlikely: There is a difference in color. Between the basal cell and skin but part of the basal cell may not be readily noticeable until a biopsy and be the same colr as the skin.

Depends...: In contrast, melanomas are typically pigmented like a freckle or mole. Basal cells are usually not pigmented (but they can be). They do have a distinct apperance: typically pearly in appearance with prominent blood vessels and sometimes ulceration. If you notice any such lesions, have them checked out.

Yep: It can, but usually it is raised.

Yes: Yes, it can be the same color of the regular skin and so can other skin cancers.
