Unable to change heading color in widgets

hi Kharis i am unable to change color of any widget heading in darker backgrounds the process in the theme wont work plz let me know if the screenshot url works here

Dear Fatima,

Firstly, you should need to give your row a custom class name, e.g. .my-darker-row or whatever you wish. http://d.pr/i/129GD

Then add the following CSS code through the Simple Custom CSS plugin.

.my-darker-row .widget-title{
  color: #ff0000;

Adjust the row class name .my-darker-row and the hex color value to your own.

I hope this reply helps.

Warmest regards,
