Stats Preview Card

I got 2 questions in this challenge.

1. I put a violet colour overlay on top of the image but the colour is way too difference from the design. Style guide has no instruction to that. How could I make the colour as the design does?

2. I don't know how to determine the media query breakpoint for my responsive design. Style guide said Mobile: 375px, Desktop: 1440px. What does it mean? I try to use (min-width: 1440px) as desktop breakpoint but it doesn't seems to be a correct way to me. Could anybody give me some ideas how to start working with responsive design?
