My current theme is wood, I don't like the effect of the menu, I hope I can use the effect of https://riftheme.com/lander/, slide the mouse down, and the background of the menu appears black.
In Customizing → Header settings →Type, variant, background set your values for colors as you wish header should look at the top. Next in Customizing → Header settings → Sticky header - Override normal settings set values for colors of the header when page is scrolled down.

I don't understand what you mean.
However, all settings for the menu and header are available in the Customizer:

I don't know which one is named "wood". Could you share a link?
With kind regards.
