I had received this answer in regard to the font color for the price and quantity count on a product item card:

In the shopping page (product catalog object) step4, you can select under elements different options.  Under details you can set the color, and also select what options you want to show. Check also the other settings in this pulldown.

Under details, the font is defaultly set to a "light grey."  This light grey setting will apply to the Category name under the product name (which is black and a couple font sizes bigger), the price and the quantity box are light grey, (the description defaults as black).  It gives the impression of the price being faded out, like when you attempt to choose a setting from a Windows drop down menu and it is grey-shaded, thus inactive.  This kind of makes the price look inactive and quantity available questionable.  I do understand how to go through each product card, one by one, and set the font to BLACK.  But how come the program sets this to light grey as a default?  How can the default settings for this be changed to black - sitewide, for every new product item created?  Seems a software engineer would need to change this in the program if the end user does not have a universal flip switch....
