Are Wella hair products quality and safe products for beginners?

I am new to hair coloring, and I am quite apprehensive about the quality of hair color, as I have a presumption that hair colors tend to gray hair quite soon! I have seen my sister, who has to color her hair every weekend to cover her grays. Nonetheless, she started coloring her hair quite early and that too without bleaching! I am 19 years old, and I wished to color my hair red for the wedding of my boyfriend’s sister. Can some hair expert please advice if Wella hair products are good enough for a beginner like me? Moreover, I am quite skeptical about red color, and I wanted to confirm whether Wella provides a quality red color, unlike Garnier nutrisse! Please help me with an appropriate advice! Thanks.
