There was a time I didn't like them together (probably back in the day when all our mommas were talking to each other and telling US their strong opinions, too). But I'm okay with them now. Strawberries are different shades of red in the same basket, and they work. If it works in nature, it works! Red and pink flowers in the same bouquet? Yes! Red and pink leaves in autumn? Gorgeous! But you wanna try to keep them both "cool" (blue undertones) or both "warm" (yellow undertones) . Except that I don't care for warm pink because that's what I call peach. Yuck. Saw that too much in the 80s and it can stay there for all I care! LOL.
If you're uncertain, please do post pictures. We can offer our feedback. Might not agree with each other, but hey, we're reds and pinks in this group! LOL
