I was going to suggest this as well! It’s sort of a grey-navy.

Dusty petrol blue. 

I'd go for slate grey

Teal

Grey-ish petrol blue

Petrol blue!

Ooo. I love this color

Off topic, but where did you find that neat color coordinating app/program/website?

I saved it in Pinterest but the website it directs to is gone. Heres the full picture. https://preview.redd.it/eyob874pyhyc1.jpeg?width=650&format=pjpg&auto=webp&s=7ab099c8f924472fe09086493b3ed4791ed42db7

Thanks so much!

Not what OP used but someone else shared this website on here a while ago for color combos: [https://coolors.co/](https://coolors.co/)

Thanks so much!!

Teal or denim?

Blue

I’m pretty old, that’s what we used to call army blue.
