Dropdown form field placeholder text color

I’m having a hard time trying to get the placeholder text for my dropdown to be a different font color.

I understand that the first choice can be my placeholder. That’s solid, but I can’t seem to target just the first ‘option’ element to have a different color.

.lp-pom-form-field select option:first-child does not change the text color.
.lp-pom-form-field select does change the text color, but it does for all the options, which can confuse any possible leads.

any help would be appreciated.
