Field placeholder textcolor is too close to a completed value

[PieterL75]

NetBox version

v3.0.2

Python version

3.7

Steps to Reproduce

1. Edit an object
2. Check the color different between the 'placeholder text' and field that has a value entered.
   

Expected Behavior

The prefilled, assisting text should be much lighter, thus less eye catching.

Observed Behavior

The placeholder text and the data text have almost the same color.
This makes the form look like it is completed with data while it is not

Jeremy, thx for taking care of it...
I would even go for a more faded color like #dee2e6, making the actual value stand out even more
