Donation Form Fields washed out by background

I have a background image on my website, and the donation form fields blend right in with it, making it very difficult to see. Is there a place where I can edit how they display? Basically, I would like the text box to have a heavier/darker outline, and perhaps for the background of the form field to be white instead of translucent. See the attached photo for example of what I mean...

Hi

Please send me the link to the donation page. I will ask my template developer to look at it and guide you

Regards,
