Change highlight colors in omnibox in google chrome theme manifest.json

Question

Can I change the highlight color in the omnibox? If so, can I change the color of the text that is highlighted? What element(s) should I be using? The default colors are a dark blue for the highlight color and white for the highlighted text color.

(I am making a google chrome theme.)

Answer 1

Themes can customize some of the colors of the omnibox, specifically text and background, not the highlight.

P.S. Extensions can't do it.

Answer 2

You actually do have control over the omnibox color. On Mac OS it is the accent color that defines it. On windows it is the accent color but you need to enable the accent color in the title bars and window borders option.
