Huevex vs Realtime Colors: previewing a palette, or carrying it into the build

Realtime Colors shows your colors and fonts on a real website layout, and it is free. That answers "does this look right?". Huevex picks up where the preview stops: it scores whether the palette holds up as a UI, then turns it into shade scales, status colors and tokens you can ship.
