In a Title, how do I create a sort of marbling of color?

[Meenie50]

I'm on a Win10 computer. 
I'm an affinity photo newbie  
I'm working on a book cover and I want to have a sort of marbleizing of color, or a swirl of a darker shade within the color of the text of the title. 
I've tried adding shadows, and I can do that to the outside of the text, but not having much luck on the inside.

You could play around with using an elliptical gradient as the Fill for the text. For example, here's a basically orange title with an elliptical gradient running from purple to orange applied:

Here's the Fill dialog (from the Context menu) that I used to do that:

There are more complex ways to use gradients, so if that's what you want you might look at the tutorials, such as

Try nesting a couple of wiggly curves within the text. Give them a different colour, and perhaps a small gausian blur, maybe a bit of transparency.

Alternatively make yourself some reusable Styles the way you want/need or reuse some already available here (take a look over the resources section or see some here, there are a bunch of those).

I guess it really depends on what your idea of "marbling" is.

I'd start with an image (or gradient or color splotches or anything with some variation) with roughly the palette you want (you can add in as you go).
Switch over to Liquify Persona and just let loose. You really don't even need any instruction. Just try all the tools. Can be as tame or crazy as you want.

Ah yeah I see, uuhhh everything's so fluid and colorful here...

There are so many ways you could achieve this using layers/masks/brushes and vector elements:

Personally, Using just the graduation tends to look a but flat...you could try adding some texture or creating some additional vector elements to be layered with the text:

Added a sample sheet with a number of options...I am sure there are many more...but that's part of the fun!
 

1.If you want to just stick to vector..try combining small irregular shaped elements into a group and apply subtle transparencies and colour graduations separately to each element (You could use the style panel to help you with this). Use Text as Mask Overlay (Mask to Below on layers panel)..so non destructive effect

2. Create a Pattern Brush using a tiled pattern and add to Base Texture of Brush. Again use Text as Mask Overlay (Layers)/or Select text element in Pixel Persona (Selection Mask)..and paint into shape

3. Same method as 2 but use a textured brush (combine a selection of nozzles) created from other images or found in resources!

4. Use a combination of graduated overlays (graduated rectangular elements)+Vector textures (Grouped random patterns created from multiple shapes) + Texture Brush in Pixel Persona

Hope this helps

An example from meanie50 would be good?

omg Thanks for the Resources ! I got stuck in the fonts already, rofl. Fabulous info, thanks!

Wow, this is fab!! Thanks! Some of that may be a bit above my pay grade right now, lol... but I'll learn it!!

Awesome... the gradient worked great. The name of the book is Bitter Prophecy so I wanted to convey the "bitter" with some darkness within the font. Thanks so much. Can you tell I'm still learning my way around. 
I tried so many different ideas on my project that I crashed the app, rofl.
