It's hardcoded into the function call. Again we end up doing a little string manipulation to get this to work "just" right.
This is the normal call:
Code:
aspdnsf:GetVariantPrice(VariantID, number(HidePriceUntilCart), Price, SalePrice, ExtendedPrice, Points, $pSalesPromptName, TaxClassID)
Wrap it in an aspdnsf string replacement to find "color:red" and replace it with whatever color you'd like...IE "color:green":
Code:
aspdnsf:StrReplace(aspdnsf:GetVariantPrice(VariantID, number(HidePriceUntilCart), Price, SalePrice, ExtendedPrice, Points, $pSalesPromptName, TaxClassID),'color:red','color:green')
