Changing color in textarea placeholder text

Hi! I'm having trouble changing the color of the placeholder text in textarea's It comes in light gray against a gray background. I'd like to make it black. Am I missing that option in the form editor? 

here's a screenshot:

Yes, its possible:

Add this CSS:

*::-webkit-input-placeholder {
   color: black;
}
 
*:-moz-placeholder {
   color: black;
}
 
*::-moz-placeholder {
   color: black;
}
 
*:-ms-input-placeholder {
   color: black;
}

How to Inject Custom CSS Codes

Hi!
Thanks for your reply. I injected the CSS, but the placeholder text still
shows up in very light grey *when I click "preview form"*.
Thanks!

Try adding the following CSS instead:

.form-custom-hint {

   color:  black !important;

}

Here is how the form would look with the code added:
