◇ Could this help me?
Yes. Generating several visual directions before committing, and grounding them in what real products actually do, is the practical way to get past the default generated look, and all three tools are ordinary public sites with no risk attached. Treat the generated directions as a starting point to edit rather than as finished design. This is a general practice.
I am starting a website and I do not want the default generated look. Give me four genuinely distinct visual directions for the project I describe. For each, specify the color palette with values, the type pairing and scale, the spacing rhythm, the motion character, and one signature detail that makes it recognizable, and name a real product whose design occupies similar territory so I can go look at it. Then let me pick one and expand it into a full spec.
