Repair your slab or pour new decorative concrete
If your slab has sunk, tilted toward the house or broken up, I'll tell you plainly that it needs replacing, because new color on bad ground just cracks again. A sound, level slab with a hairline crack or two can often be repaired and kept. A stamped pattern is pressed into fresh concrete, though, so if it's the stamped look you're after, that means tearing out and pouring new over a proper base.
