Is there any Halacha or Minhag that specifies if red or White wine should be used for the four cups of wine during the Passover seder and does it matter what you use to spill out during the 10 plagues?
Not only is it a Minhag those who say Yotzros on Shabbos Hagadol say it in there יין כי יתאדם למצוה הוא מקדם Translates as "Wine that is Red for the Mitzvah ahead" Not only that the Rambam sas you are not Yotzeh using white wine for kiddush( we do not Poskin like that) and the Mishnah Berurah adds Pesach there is another reason to remind us of the of the blood of the Jewish children Pharoh used to Bathe in.
Dittos to YS. The reason that many Ashkenazim stopped using red wine for the seder is because of the blood libels, but today (unless you live in an Arabic country) this is not a concern and therefore it is preferable to use red wine for the four cups at the seder.
The Rav, Rabbi Joseph Ber Solovetchik, says to have red wine for the first cup [Kiddush], to signify Cherut (≈freedom).
