Hi zvei dinim. Thanks for your response. However, it’s not so clear.
The Mechaber (Shulchan Aruch, Siman Tet, Saif Heh) seems to indicate the validity of colored Tzitzis on a Tallis with a the same said color, but the Rama is concerned:

and the ???? ????? ???? ? ?”? ?? rules:
?? ?????? ?????? – ?”? ???? ?????? ????? ???? ?’ ????? ?? ?”? ??? ??? ????? ??? ??? ??? ?????? ?????? ????? ?? ???? ????? ??????? ???? ???? ??? ???? ???? ???? ???? ??????? ???? ??? ???? ???? ??????:
The Mishna Brura is stating that to be Yotzei all the opinions … Could he be hinting to that Tosefta which disqualifies any dye, save for Lavan and true Techeiles?
I don’t know …. Tzarich Iyun.
