My placeholder text is two different colours

Design help General

The placeholder text in my form is two different colours. I’d prefer it to be the lighter colour (as seen in the CVV field, for example).

Any idea why this is happening and how I can fix it?

I’ve added custom css as per the post below. But still the placeholders are different colours.

Hi, do you want all labels in that form to be that color of the text in the CVV box?
