Site Content > Page Titles > Background Color uses old palette in live preview but the palette shown in the Customizer is the new one. Front end also shows the old palette color.

Site Content > Links > Link Color
Live preview shows old palette but the front end is correct.

Design > Blog > Blog Page > Background Colors

I have no clue where it's getting the colors from for the Post Header. I have the featured image hidden. Front end is correct tho just a live preview bug.

Design > Blog > Blog Page > Post Meta > Date Link / Author Link Colors > Custom
Live preview bug front end is correct

[nicolepaschen]

Design > Blog > Blog Page > Read More Links > Link Custom color
Live preview bug front end is correct

[nicolepaschen]

I'm going to guess that Blog > Blog Page > Links > Tag Links, Category Links, and Comment links will have the same live preview issue.

Old palette still shows on the sidebar however the live preview uses the new palette
Footer Column 1 2 and 3 also show old palette

Design > Blog > Posts > Post Meta > Date / Author Link Color > Custom
Live preview shows old palette front end is correct

[nicolepaschen]

Design > Blog > Posts > Links > Post Navigation Links > Custom
Live preview shows old palette front end is correct.

Design > Blog > Posts > Links >
Going to guess the Custom option for Tag Links and Category Links are incorrect as well.

Header > Background > Header Overlay
live preview AND front end show old palette with a YouTube video background or image background
