In the middle of the article, there is a brief discussion about icons and colors. I also think that well-coordinated color icons are good for readability and usability.

However, it is difficult to apply it universally to support a variety of colors. If it is similar to the background color, it is difficult to distinguish and there may be contrast issues depending on the light/dark theme. I think it's just the ease of development of a solid color icon that matches the color of the text.

Oh, I missed that. It's satisfying to see what I assumed to be true to be laid out so concretely as data points.

I just wish it was something more 3D and "skeuomorphic" instead of just making a flat gray arrow into a flat green arrow. For example, if Chrome used a yellow star instead of a white star outline, I bet a lot of people would say it looks ugly as hell and sticks out like a sore thumb, but I'd prefer it. I can barely tell these monochrome icons apart.
