Change the color of the labels of the text fields on the checkout page

Hello,
I want to change some of the colors of the texts on the checkout page because they don’t have good contrast.
In the theme, the colors of the forms are different from those that appear in the checkout, and I don’t know why they are not reflected.
How can I change this?

I am attaching an image of the text color I want to change, it would be the color of the labels of the forms and the titles of your order. I don’t see a way to change them.

Hello,

Is there any chance that you could give me access to the dashboard area so I can have a look at the settings on your website, please?

Kind Regards
