The impact of templates on click-through rate

Recently I have been testing the impact of templates on click-through rates, mainly comparing data from Google Adsense and 2bj.
It turns out that the impact is quite large, especially for dark templates (such as black), the click-through rate will be much higher.
However, if the click-through rate is high, there will be more invalid clicks, and the total price of Google Adsense will not change much. (It is said that Google controls the total daily revenue of each site, which seems to make sense.)
However, other click-based ads will see an increase in revenue.
There are pictures as evidence:

The 23rd and 24th are black templates, and the 25th is a classical template.
Therefore, to increase income, it is recommended to use a dark template, but it affects reading.
Weigh it yourself.
