Ha! A seemingly simple question but one that is fiendishly difficult to answer!
The "look" of a fractal is largely down to your choice of formula and the colouring algorithm that you apply. The possibilities of just these two elements in the fractal design process are enormous. Your taste and preferred style will dictate much of what (and how) you achieve the look you want. Some artists like constructing complex patterns or textural works, others work almost exclusively with abstracts. Me, I'm usually an orbit trap gal, I love spirals and distinct shapes. I know a lot of UF artists through Deviant Art and the most amazing thing is that most of them have very distinct personal artistic styles. So as well as the possibilities UF offers with its formulas there is the added element of the artist him/herself, stamping their ideas, style, colours etc on the finished product.
So without knowing what you like and what you want to achieve it's rather difficult to advise.
I would suggest you initially try to familiarize yourself with a restricted choice of just one or two basic formulas and pair these with one of just a few colourings. By limiting your choice for a short while you will gain some valuable experience which you can later apply to other combinations. I say this because it's easy to get overwhelmed by the thousands of possible formulas and colourings that are in the database, many of which can be quite difficult if you are new to the program and you just end up running round like a headless chicken, not knowing where to start! Sound familiar at all?
For formulas start by using a basic Mandelbrot or Julia formula from Standard.ufm (on the Formula tab) together with one of a basic “toolset” of colouring algorithms (on the Outside tab)...
Here is a short list of colourings that I have found to be relatively easy to use and very flexible, giving
interesting and fun results almost straight away (use on Outside):
- Orbit Traps (UF3) in dmj3.ucl
- Doodads and Thingamajigs in ldm.ucl
- DoodadsII, ThingamajigsII, Plane Curve Traps II and Thin Orbit TrapsII in tma.ucl
- Gaussian Integer and Triangle Inequality Average in Standard.ucl
- Whimsical in jam.ucl
In my experience it is much more common to use the colouring on the Outside tab. Certain formulas require Inside colouring and some can use both but you will most likely be using the Outside to start off with.
As for gradients you could try using a greyscale gradient to start off with - experimenting with shape and design without the distraction of colour can be helpful. When you find an image you are happy with you can introduce some colour to liven things up a little. Add one or more duplicate layers and try different gradients on these with different Merge modes. You can get UF to generate randomized gradients which can be fun (F5-F8 keys on Windows, I don't know the Mac equivalent). Play with Color Density and other settings at the top of the Outside tab (these affect how actual colours are applied to the fractal).
As experience grows you can slowly try new formulas & colourings. Or load up some shared parameters* and look at how the artist used formula/colouring combinations to make the image. Maybe take a layer from this and use it as a starting point for your own exploration (please credit original artist if you do this unless your tweaks are so far gone that there is no hint of the original). This might be the best way of finding what formulas/colourings produce the sort of thing you want so look around for images you would like to make and have a good poke around the parameters! In time you will begin to understand how to go about getting a particular shape, effect or texture and then you will be able to be more purposeful in your image making. Until then you need to practice, experiment and carefully observe how things affect a fractal. Make notes, save good combination layers for later use and don't be afraid to dig into the parameters!
