How get white-bright fonts a little bit dimmer?

I use "monokai-pro-octagon“ theme but find its default text color much too bright, ​ https://preview.redd.it/ovlo0n2symv81.png?width=697&format=png&auto=webp&s=e4f5bc8ca2de6c2211f469a8e7a277dd5db60808 in org doc: https://preview.redd.it/nj05hytzymv81.png?width=940&format=png&auto=webp&s=b46c91ed01b76bbbb1d958d0a731c4b1d7a54296 How could get it a bit dimmer?

Easiest way is to pick a theme that you prefer.

I prefer this one excluding the bright white text.

Then have a look for a similar one [here](https://emacsthemes.com/). Or, find out which faces you need to modify by putting the point in the relevant place then typing `C-u C-x =` then [customise them](http://www.gnu.org/software/emacs/manual/html_node/emacs/Face-Customization.html).

thank you, the themes really helps.

Put the point on the text face you want to change and type `M-x customize-face`. Now pick a new colour. You can use any colour you like, but I think `M-x list-colors-display` is useful for inspiration.
