In AUCTex there is font-latex-math-face which makes color of string in between $ and $ as green.

Example output:

Is is possible to disable/delete font-latex-math-face, where the green color won't apply?

There is no built-in way to enable font lock inside a math environment, but you can prevent AUCTeX from recognizing the dollar as a math delimiter replacing the definition of font-latex-match-dollar-math with

(with-eval-after-load 'font-latex
  (defun font-latex-match-dollar-math (limit)
  • It made string color in between $$ all white which is now more difficult to read. is it possible to keep the normal coloring

  • Prefered color is default face I believe , where it also changes coloring text based on the key words like \mathrm should be blue and so on. I have put the color change in my question. Is it possible to keep the original face colors?
