Custom Theme from Two Themes


#1

I like the ‘Atom Material’ theme (first picture), especially the colors for the words. But I like the fact that the upper and lower bars are white in the ‘Material’ theme (second picture). Can someone please make a theme which is exactly the same as the first theme (Atom Material) except that the upper and lower bars are white in it like in the second theme (Material), or teach me how to do it? Thank you.
I am just starting to learn how to code.
