One brand across every document, sheet, and deck
All three surfaces read the same Brand Kit your website reads, so you set the brand once rather than per file.
To set it:
1. Open the Builder shell and pick the Design group, then the Brand Kit pill.
2. Set your accent color, brand color set, font pairing, and logo.
3. Save. Decks pick the palette up in their theme; docs and sheets pick up the same colors and type.
Two things that follow from sharing one brand:
• Change the accent later and everything you have authored restyles with it — you are not hunting through old files.
• The asset library is shared too. An image you upload for a website block is already in the picker when you are building a slide, so logos and product shots do not get re-uploaded in five slightly different crops.
If a deck looks off-brand, check whether someone overrode a color on the individual object — per-object overrides beat the theme by design.
