- Take a paint tray, put a generous amount of (dark but not anywhere near black) gray paint
- Add a pretty nice glob of white paint in the middle of the tray. Less is more!
- Take a rough roller (one that's been nicely loved), roll it in the tray so that the outside of the roller is soaked in gray and middle in white
- Paint your walls
- While still wet, go over the walls with a roller and minimal gray (like dry brushing but with rollers, fuzes the white together while keeping the rough concrete texture)
- Stand 20 ft away and see if the white is random enough. If not, the wiki recommends you take more grey to certain areas and not others.
