Custom code for product item nav not working

Hello, I'm trying to change the colour of text in my product navigation bar.  I've had to do lots of code despite changing in site styles but I still can't change the font colour.  Current CSS is below and everything has changed except the colour. I've tried changing to RGB HEX etc. and still no luck. It won't change from pink. 

.ProductItem-nav {
  font-size: 10px !important; color: black !important;
   font-weight: normal; font-family: 'raleway' !important;
}

I am also having the same problem with product QUANTITY, I can't get it not being bold

Can you share your website URL?

You can try this Custom CSS for quantity to be bold:

.ProductItem-details .quantity-label {
    font-weight: 900;
}

Sorry I want it not to be bold! but i've changed the weight on that and it's worked, thank you so much

This is the breadcrumb navigation color CSS:

.ProductItem-nav-breadcrumb-link, .ProductItem-nav-pagination-link {
    color: #ff8fd2 !important;
}

Change the #hex to whatever you want.

hhm the mystery continues, that doesn't work - I've tried something similar I found online

Have you tried adjusting it in the color theme in the styles menu?

What's odd is the colour doesn't even exist in the styles menu anymore. I perhaps have some code in there that is getting in the way but i can't seem to find it

But the colour neither exists in the css or in the themes/styles as far as I can find

It must be in there somewhere, if you temporarily delete all of the CSS does the colour change? (Make sure you copy it first!)
