桥接模式比较合适，下面是一个例子

```go
// 实现部分
type DrawAPI interface {
drawCircle(radius int, x int, y int)
}
type RedCircle struct{}
func (r *RedCircle) drawCircle(radius int, x int, y int) {
fmt.Printf("Drawing Circle[ color: red, radius: %d, x: %d, y: %d]\n", radius, x, y)
}
type GreenCircle struct{}
func (g *GreenCircle) drawCircle(radius int, x int, y int) {
fmt.Printf("Drawing Circle[ color: green, radius: %d, x: %d, y: %d]\n", radius, x, y)
}

// 抽象部分
type Shape interface {
draw()
}
type Circle struct {
x int
y int
radius int
drawAPI DrawAPI
}
func (c *Circle) draw() {
c.drawAPI.drawCircle(c.radius, c.x, c.y)
}

// 使用桥接连接抽象和实现
func main() {
redCircle := &Circle{1, 2, 3, &RedCircle{}}
greenCircle := &Circle{4, 5, 6, &GreenCircle{}}
redCircle.draw()
greenCircle.draw()
}
```
