Color palette → reference file → new style → applied to a real library. The whole loop, including the "be bold" trick that keeps AI from second-guessing itself.
The video kicks off the new style by asking Copilot to generate an image color palette. The output is a blueprint-style image with a swatch strip across the bottom. SharePoint doesn't have to match the image exactly — what matters is the palette swatch and the mood it captures.
The image becomes a concrete artifact the next AI call can read. It is much faster to describe "use this palette" than to enumerate hex codes, and it gives the style file a piece of visual evidence to lean on.
AI styling has a known failure mode: the model is trained on every style ever made and starts second-guessing. Did you want subtle? Modern? Avant-garde? When it is unsure, it produces a timid output — restyling just the header or the icons and leaving the rows alone.
The same pattern shows up across AI styling tools in general. Without an explicit nudge, the default behavior is conservative. With one, the model commits — replacing row layouts, changing the whole vibe, taking the kind of swing you actually wanted.
Once the style file exists, applying it is the same shape as any AI in SharePoint call: a prompt that names the List Styling skill and tells it to use the blueprint style on this library. The author was explicit about which skill to use because their tenant had several style-related skills installed and they didn't want any confusion.
Styling is not the fastest operation — but it is not human-slow either. The model has to read the style file, write the row formatter JSON, apply it to the library, and verify it took. A few minutes per style is normal.
To demo a new style, the author uploads a few documents and then asks the AI to fill in random metadata. With realistic-looking values across status, owner, due date, and other columns, the style finally has something to render — red overdue chips, blue active rows, the whole blueprint vibe.
This is also a fast way to test conditional styling. If "overdue" should render red, you need an overdue item. If you want to see the green status pill, you need an item in the right state. AI-generated random metadata is the cheapest way to get there.
