Change font color on Contact us form

How to change font color on “Contact us” form. My font is bright RED. I would like to change it to black. I way able to change some things under setting Style: (form 1)Modifiable CSS Style. Did not see a option to change color of font. Except I did see “CSS style for form input errors: text-align:left; color:red;“. That was the only field I saw related to color of font.

Thanks for Help
