The tzitzit are supposed to be the same color as the beged according to the Rambam. Is that a problem for people with those colored talliyot or is it that it just has to be the same color as that little square in the corner which is kept white?
Also, if a person holds by techeilet, and it's not really techeilet, is that a problem with respect to this halachah of the tzitzit being the same color of the beged [presumably the one exception would be for real techeilet]?
