What makes a 'good' brand guide for PaletteCheck extraction?

After working with many brand guides, here's what produces the best extraction results:

Essential Elements:
✅ Color swatches WITH hex codes (not just visual)
✅ Font names explicitly stated (not just shown)
✅ Brand voice described with specific characteristics
✅ Clear do's and don'ts for logo usage
✅ Text-based PDF (not scanned images)

Nice to Have:

• RGB, CMYK, and Pantone values for colors
• Font weights and sizes for different uses
• Example content showing voice in action
• Photography style descriptions

What Doesn't Extract Well:

• Colors shown only as images
• Fonts displayed without naming them
• Vague descriptions ("be professional")
• Scanned or image-only PDFs

Pro Tip:
Even a simple 5-page guide with clear specs works better than a 100-page guide with everything as images.

What's in your brand guide that extracted really well (or didn't)?
