I currently have products with 24 different color choices, which are priced in 3 tiers. I want to add tier 4 pricing to the existing with corresponding colors. But I cannot find where to do that. My input page allows me to enter the Tier prices for the color choices. This may be a development issue that is connected to the theme?
It sounds like you may have the Tiered Pricing Table for WooCommerce extension installed, which adds the ability to create dynamic pricing for WooCommerce products based on product quantity, or by variation (in your case, color).
If so, you may want to review the documentation for that particular extension, which describes the steps needed to create tiered pricing levels and apply them to individual products. In particular, scroll down to the Variable Product section.
Hope this helps!
