We know officially there are no women or colored people credited on the constitution itself but i am curious if any of their beliefs changed or were influenced during the writing itself. Did any of the founding fathers hear from constituents while writing it and thus had debate and even changed their opinions? Did they have advisers or any documentation to that effect?
This does not address the entire scope of your question, but there is a bit beyond Abigail Adams' famous advice to her husband and her line "in the new Code of Laws which I suppose it will be necessary for you to make I desire you would Remember the Ladies, and be more generous and favourable to them than your ancestors. Do not put such unlimited power into the hands of the Husbands."
It appears the first hurdle was the extreme secrecy under which the new Constitution was being discussed, and the second was the exclusion of women in politics at the time. Richard Beeman in Plain, Honest Men writes:
Looking back on the summer of 1787 and on her role as hostess for the Convention delegates, Elizabeth [Powel] spoke of her pride in having been "associated with the most respectable, influential Members of the Convention that framed the Constitution, and that all the important Subject was frequently discussed at our House." Elizabeth did not hold back on giving her own views on that "important subject." Indeed, she made it clear to those in her circle that she was both proud and unafraid of engaging Washington and other Convention delegates about the seminal topic of that summer. We have no record of her contributions to those conversations and, indeed, such was her discretion that she would have considered it a break of honor to have revealed any of what was said around her table. But based on the late rFederalist political allegiances, she openly expressed as a leading Philadephia saloniste during the 1790s, we can imagine that, as one who later became an outspoken supporter of the Federalist Party, she almost certainly would have sided with the large-state nationalists in preferring a system of proportional representation (emphasis added)
Beeman also mentions Powel's niece, Anne Bingham (who, incidentally, was "by many accounts the most ravishingly beautiful young woman in America"), as a woman with whom Washington enjoyed company:
[Powel and Bingham] created an atmosphere in whcih the delegates to the Convention could not only relax and unwind, but where they could also bend just a bit the strict rules of secrecy that governed their proceedings....Anne, like Elizabeth Powel, was fearless in speaking her mind about any and all of the issues confronting the new nation
