A couple of comments;
1) Why did you choose green? By your own chart/data you showed that 57%(men) and 35%(women) liked blue. I understand that money is green however a majority of financial and investment apps actually use blue more often than green
2) You don't really speak on product at all which is a HUGE part of the UI decisions about color. Depending on the product, and the goal, the whole color psychology changes. Not to mention branding having a big part in it all. You tell Bank of America or WellsFargo they cant use red because they're financial products
An otherwise good article, I think there just needs to be a little more, its a great start, thanks for sharing!
I understand your points. but my main goal was to show how color can affect things. and yes if we talk about products/brands, there's a lot of things and I can write another article on that topic. I am glad you liked it. will share more stuff.
If you're writing about colour in UI you really should also mention accessibility – contrast. Too many designers overlook the fact that colour contrast makes text legible. Even his final design wouldn't pass wcag.
Cool article. Usage of colors can be a great tool, and determine the success/failure of a project.
For example, this was pretty successful back in the day: https://www.quads-puzzle.com/
