Header image in the Row not displaying & colors not changing on mobile version

I was given the task to update my company’s website with their new colors and new logo, this included adding the new logo to current images. I have done this and on the home page, I uploaded and replaced the original image with the new version however it doesn’t show up on the page, it does show up in the edits but not on the actual page. I have cleared the cache several times.

Secondly, I have updated all colors to reflect the new colors, HOWEVER on the mobile version the old colors are showing up in certain instances.

I have gone through the entire css twice to find any instance of the old color but I cannot for the life of me get these two items fixed.
