Social proof section with SASS

Hello there! This has probably been the most frustrating project so far for me, mostly due to the background patterns on the mobile version. I'm not sure how other people managed but I had trouble seeing the bottom background pattern on mobile, even after straining my eyes for 20 minutes I was still unable to see the pattern. Eventually, I found a trick with IrfanView where I'd enable Negative mode and the pattern was more visible.

For those who managed to finish this project, I am very curios to hear if you've encountered the same problem I had and if so, how did you overcome it? I'm really curios to hear if I was the only one with bad eye sight or if this is a common occurance when dealing with such semi transparent and hard to see patterns.

Any advice or suggestion is welcome! Thank you in advance! ^^
