The 3 colors look distinct to me. My only issue is that if all 3 colors were in use by 3 different players on the same roulette table, it would be difficult for the dealer (and players too) to keep them straight.

Could the Teal have been a reorder for the Light Green, or vice versa? I didn't look to see if order cards exist for these chips.

Regardless, they are classics with a great Dunes graphic. Love 'em!!!
