Amber-colored top.
At the start of the battle, a random number from one to seven is chosen, and a number of red stars equal to the chosen number appear on the top of the ball. These stars can be seen on the ball's sprite in the bag. All of the Dragon Balls used during that battle will have the same number of stars on them. The number of stars will persist after a successful capture, so a Pokemon caught in a five-star Dragon Ball will always show up in a five-star Dragon Ball. On each turn whose cardinality is congruent to the chosen number modulo 7, the Dragon Ball will be seven times more likely to catch the target Pokemon than a standard Pokeball. (So for a five-star Dragon Ball, turns 5, 12, 19, 26, and so on would have the boosted catch rate.) On every other turn, the Dragon Ball's catch rate is just one seventh the rate of a standard Pokeball.
About halfway through this dumb joke post I realized that I'd actually like a ball with roughly this effect, so maybe we could have a ball with up to six dots on it (like a standard six-sided die) called the Lucky Ball (would've been the Gamble Ball, but we have to think of the children) with the exact same effects only with sixes instead of sevens.
