how do i customize the font on the marketpress/framemarket/gridmarket products when they are on the

i want to customize the font size and color without a global change. ie, in the customizer i can change all the fonts to a color, but i only want to change them on a case by case basis. in this case, it is when the products are shown on the home store page. when you click on them, the title shows up in black, but when they are on the store page, they are white on white = invisible :slight_smile:
for some reason i've spent hours trying to find where this font setting is - anyone have a clue?
tx!
