Fabulous, this took me right back.
I ran a project to re-platform and redesign one of our largest high street banks. We took each business line (savings, mortgages, current accounts etc) through the new layout (small, medium, large, XL - this was almost 20 years ago) as wireframes, with the candy stripes. In the savings team run through there came a voice, “I like the layout but I’m not keen on the colours, the stripes make it hard to read”. Thinking they were joking, I said, “the vertical stripes are essential to the design”. They were not joking.
All ended well in the end.
They used our design for about 10 years and now, after a rebrand, still use the same basic layouts and components, just reskinned.

If you are looking on a mobile, rotate your phone from portrait to landscape and back to see how we also used components to stack content/sit it side by side and still maintain narrow easy read columns.
I’ve still not forgotten what Jon Walsh our designer on the team told me “Alex, don’t be afraid of the white space”.
