White Fur Under Color?

[cuppa]

Hi all! Not an inquiry on breed or anything. Minnow is a DSH, and I believe her coat could be described as a point torbie with white.

But I've got some questions about patches of her fur.

• The patches all along her back only have color on the tips. It's white underneath.
• The gray patches on her feet have color underneath, but are tipped in white.
• Her tail is colored completely with no tips
• The bottoms of her feet are solid color

Is that typical? How can that be described? I'm curious about coats in cats since there's so many variations.

She’s so pretty! I think it looks like her undercoat is white. Her coloring would still be called torbie point. My Charlie also has a wooly white undercoat but, when looking at him, he looks totally orange!
