Eight bit sRGB and eight bit Adobe RGB both have the same number of colors in their gamut: 16,777,216.

The sRGB gamut encompasses about 35% of all visible colors, while the Adobe RGB gamut encompasses about 50% of all visible colors, the increase appearing mostly in greens/cyans.

Those extra colors must come from somewhere. If you add greens/cyans to the 16,777,216 available colors, you must give up some colors elsewhere in the gamut.
